Honda Lawn Mower Carburetor Adjustment: How to Do It
This post may contain affiliate links. As an affiliate of retailers(like Amazon), we earn from qualifying purchases.
When your Honda lawn mower’s engine doesn’t idle, lacks power at high speed, or won’t start, it could be time to adjust the carburetor. If you have never done this before, you are probably wondering how difficult it will be, what tools you will need, and if you should just call an expert.
Adjustments to a Honda lawn mower’s carburetor should be made after it has been cleaned. If the carb is dirty, adjustments will be temporary. You will need some screwdrivers, a wrench, a carb cleaner, and an hour or two. Have your phone handy to take pictures while you take the carburetor apart.
Keep reading to find out how a carburetor works, what could be causing different problems, as well as preventative measures.
How Does a Carburetor Work?
Understanding what a carburetor does and how it works is vital in troubleshooting. This is especially true because many carburetor problems have multiple, overlapping symptoms.
The carburetor’s role is to provide the space where gas and air mix. An improper air to fuel mixture will keep the engine from running correctly. An incorrect gas and air mix cause most carburetor problems. Your job is to figure out what is causing the mix to be off.
- Float Chamber: The float chamber holds fuel, and as the amount of fluid increases, the float rises until it is pushed into its seat. When fuel leaves the chamber, the float falls. As more fuel enters, it rises again.
- Intake: Air rushes through the throat of a carburetor, and then a narrower passageway called a venturi. This causes the air to speed up, creating a vacuum that pulls fuel into the fuel nozzle.
- Fuel Jet: Once the proper gas/air mixture has been created, the fuel is pulled through the fuel jet. This creates the explosion that powers the engine.
- Throttle Valve: This valve controls the amount of gas that goes into the carburetor. An open valve increases the engine’s power, and a closed valve stops the engine.
Carburetor problems can occur at each of those points, and the way to fix most carburetor problems is to get inside and see which of these is causing the problem.
Why You Should Clean the Mower’s Carburetor
Although you might be tempted to play around with the throttle or make other adjustments, clean the carburetor. Otherwise, any corrections you make will be temporary, and you could wind up causing even more damage to the carb.
Also, get a parts cleaner, such as WD-40 Specialist Carb/Throttle Cleaner. It contains the solvents you need to clean out the gunk, and the spray will blast away dirt and deposits. For tools, you will need screwdrivers and a socket wrench.
Mower Engine Starting Problems
If your engine is not starting, you have difficulty starting it, or it stops after you get it started, then the following could be causing starting problems:
- The main jet, main nozzle, or main nozzle air path could be clogged.
- The float isn’t moving correctly.
- The throttle stop position is wrong.
Mower Speed Problems
If the engine speed does not increase, the speed is unstable, or the engine performs poorly at high speed, then an additional clog to check for is the pilot jet—either its air path or the jet itself are clogged.
Should speed problems happen at low speeds or the idle speed is unstable, then in all likelihood, the pilot jet or its air path is clogged. You will need to check for dirt and clean.

Mower Gasoline Problems
If gas is leaking from the carburetor, then the problem lies with the float valve. Either the float valve is worn out or coated with dirt, or the valve seal is worn or dirty.
Getting to the Mower’s Carburetor
Before you get started, we recommend you disconnect the spark plug cap. This is to prevent the mower from accidentally starting. Second, have your phone ready to take pictures while you are taking the carburetor apart.
Fix Without Taking the Carburetor Apart
You might get lucky and avoid having to take the carburetor apart. To do so, FOCUS on cleaning out the carburetor idle jet. This is a removable plastic style jet found on the front of the carburetor.
- First, spray the carb cleaner and remove the dirt and gunk.
- Look for a plastic screw with a Phillips head bolt. That’s the idle adjustment screw. Loosen and remove it.
- Now you will have access to a rubber plug with a hole. This is the idle/pilot jet.
- To remove the pilot jet, you need to pull it out gently. Use flathead screwdrivers to wedge it up.
- After you get it out, you should clean it with the carb cleaner. The small hole on the end often gets plugged. Honda makes Jet Cleaner sets, but a tiny pin will be a good substitute.
- After you have cleaned the pilot jet, push it back in carefully, and then replace the idle screw. Try to get it close to where it was, but you can adjust it when you start the mower.
Clean Out the Float Bowl
The float bowl is at the bottom of the carburetor. It is easy to take off, but before you do, turn off the fuel line. Then loosen the bolt on the bottom and take out the bowl.
There are two gaskets—one where the bowl connects to the housing, and another one on the bolt. Inspect both for cracks. Then clean out the bowl and replace the housing.
Taking the Mower’s Carburetor Apart
If the mower is still not running correctly, then the carburetor must be taken apart so that you can clean it. This is a much more complicated procedure and could take an hour or more.
- First, remove the air filter. If it is dirty, replace it. A dirty air filter can affect how well your mower runs better. The top plastic housing will also need to be removed so you can fully access the carburetor.
- Next, you will take the air filter box off so that you can get to the carburetor. In most models, it is held on by two bolts. As you loosen the bolts, hold onto the carburetor. The bolts run through the carburetor and mount it to the motor housing.
- Now that you have access to the carb, get ready to start taking pictures. Anything you unhook needs to be hooked back correctly. Keep an eye out for the tiny spring attached to the top.
- Once you have taken the carburetor off, it is time to disassemble. As you do so, check the gaskets—worn ones need to be replaced. Continue taking the carb apart and cleaning. Every hole needs to be clear of dirt.
Finally, the carburetor will have to be reassembled. Hopefully, you took lots of pictures so that you have them as guides.
Rather than taking a carb apart, some folks simply buy a new carburetor. Be sure to check compatibility with your Honda Mower.
Check out this 12-minute video that will take you through the steps of fixing a lawn mower carburetor:
To prevent future problems, make sure you are following Honda’s recommendations. Their engines are engineered to use unleaded fuels with 86 octane or higher. Ethanol fuels can be used as long as the fuel has no more than 10% ethanol (E10). A fuel with methanol should contain no more than 5% methanol.
Copyright article owner is ReadyToDIY.com for this article. This post was first published on 2020-08-27.
Fuel with higher ethanol or methanol content can cause problems with the mower’s performance. The engine’s warranty does not cover damage to the engine caused by fuel with more than 10% ethanol.
If possible, regular unleaded gasoline is ideal. Avoid E85 at all costs because Honda considers it an alternative fuel since it is 85% ethanol and only 15% gasoline.
Storage Suggestions to Prevent Carburetor Problems
These are some suggestions to prevent future carburetor problems. Gasoline can begin to deteriorate within three to four weeks, so use these if you only mow every couple of weeks:
- Fill up the tank. As fuel is exposed to heat or air, it oxidizes and can gum up the carburetor’s jets. Keep the tank full to minimize how much gas can enter the tank through the vent.
- Run the engine out of gas. No fuel = no oxidation. If the mower only has a little gas in the tank, run it dry and close the fuel valve.
- Storage container. Make sure you close the container tightly and store it in a cool place. Honda discourages metal fuel containers since they might rust, and tiny rust particles can clog the carburetor.
- Fuel Stabilizer. Fuel stabilizers should be added if gas is stored either in the container or the mower for three months or longer. If you plan to use the mower within a year, there is no need to drain the gas from the fuel tank or carburetor—as long as you add the stabilizer.
Carburetors are an essential and often overlooked part of a lawn mower. If your mower is not running well and you have checked the air filter and spark plug, you might have to work on the carburetor. Taking the carburetor apart and cleaning it is time-consuming but not difficult. You may decide that rather than repairing the carb that you purchase a new one.

The Best Self-Propelled Lawn Mowers in 2023 for Making Your Yard Work Easier
These lawn mowers drive themselves, taking the load off you in the process.
By Roy Berendsohn Published: Mar 21, 2023
One of the perks of the warm-weather season is getting to spend time outside. If you own your own home and have a yard, it’s very likely that in order to enjoy your outdoor space, you need to mow the lawn. The larger the yard, the more work it will be to maintain. If you have a lot of grass to cut, you’d be wise to consider a self-propelled lawn mower especially now that there are a ton of sales just in time for Memorial Day.
The primary difference between a standard push mower and a self-propelled mower is that the former moves when you push it, and the latter essentially moves itself with only your guidance. Once the engine is running, all you have to do is squeeze a handle or push a lever and the mower will start moving forward with you as you walk.
Turning the mower around is your job, but once you have your heading, just keep the drive handle squeezed and escort the mower down the path, no pushing necessary.
Self-propelled law mowers take power off the engine and route it via a belt to a pulley on the transmission and axle. When you move the drive control lever on the mower handle, you tension the belt, causing the pulley to turn, and this drives the transmission, moving the mower forward.
Move the drive control lever back and the tension is released, the pulley stops turning, and the mower stops moving forward. The belt-driven transmission is a time-tested design to power the mower and take the load off you in the process.
What to Consider
A mower is like many consumer products in that the more features a manufacturer adds, the more expensive it becomes. But a longer or more eye-catching list of features isn’t necessarily better. Sometimes less is more. Here are the most important to keep in mind.
Front-wheel drive mowers tend to be less expensive than rear-wheel drive units. They can be easier to turn because you don’t have to disengage the drive wheels to do so. Simply push down on the handlebar to raise the front wheels off the ground. However, their traction isn’t as strong on hills or when the bag is full, as there isn’t as much weight over the drive wheels.
Rear-wheel drive mowers do cost more and aren’t as easy to turn, as you do need to disengage the drive—but this isn’t too much of a hassle. Rear-wheel drive mowers shine on hills and inclines, and when the grass bag is full. In either scenario, weight is shifted rearward and over the drive wheels, which enables superior traction, thus making the self-propel more effective.
An engine as small as 125 cc can power a mower, but most are somewhere in the 140 cc to 190 cc range. A large engine helps when powering through tall, lush grass or in extreme conditions, such as with a side discharge chute in place and mowing tall weeds in a border area. Also, the extra torque provided by a larger engine can improve bagging when the going gets tough (tall, leaf-covered grass in the fall). But if you mow sensibly and pay attention to deck height—and especially if you don’t let your lawn get out of control—an engine between 140 and 160 cc has more than enough power to get the job done.
A mower can have all four wheels the same diameter (7 to 8 inches), or it may have rear wheels that range from 9.5 inches to 12 inches in diameter. Larger rear wheels help the mower roll more easily over bumpy ground.
With some mowers you can start the engine with the twist of a key or the press of a button. It’s a great option, but a luxury. Keep the mower engine tuned and use fresh fuel with stabilizer added to it, and you’ll never have trouble starting.
Any number of mechanisms can control a mower’s ground speed—a squeeze handle, a drive bar that you press forward, even a dial. There’s no single right answer here. Look at the design and think about how you like to work. For example, if more than one person will be using the mower (and not all of them are right-handed), a drive control like that on a Toro Personal Pace mower might be the answer. Just push down on the bar to make it go faster. Let up on the bar to slow down.
A mower that can bag, mulch, and side discharge is known as a three-function mower, the most versatile kind. Two-function mowers bag and mulch or mulch and side discharge.
Mowers will typically have one, two, or four levers to control the deck height. Single-lever adjustment is the easiest to use, but it requires more linkage, which adds weight and complexity. If, for some reason, you find yourself varying deck height frequently, it’s a good option. Otherwise, two or four levers work just fine.
Only Honda makes a gas-engine mower with a high-impact plastic deck (there are battery mowers that have plastic decks). Otherwise, mowers generally have a steel deck, and a few manufacturers—Toro, for one—offer a corrosion-resistant aluminum deck. An aluminum deck won’t rot the way a steel deck will, but you still need to keep it clean.
This is a hose fitting mounted on top of the mower’s deck. When you’re done mowing, hook up a hose and run the mower to power wash the underside of the deck. We’ve had mixed results with these, but they’re better than just letting a mass of dried grass clippings accumulate.
expensive mowers come with a more durable bag with more dust-blocking capability. If you bag a lot, especially leaves or other lawn debris in the fall, then you need a mower with a higher quality dust-blocking bag. Having said that, if you rarely bag, the standard one that comes with a mower will last you the life of the mower.
Also called wide-area mowers, machines in this subgroup help homeowners better reconcile their need for more power and speed with the fact that they may not have enough storage for a tractor or zero-turn mower. A typical residential walk mower has a single-blade deck that cuts a swath from 20 to 22 inches wide. Wide-cut mowers (built for homeowner use) have either a single blade or, more typically, a pair of blades, cutting from 26 to 30 inches with each pass. Some of these are rated for light commercial use and have larger decks, in the 32-inch range, and engines that start at 223 cc and go up to about 337 cc.
Wide-cut mowers typically employ gear or hydrostatic drive transmissions, and they have top speeds of about 4 to 6 miles per hour. At their fastest, they move so quickly you have to trot to keep up with them. Needless to say, they’re overkill for small yards; only opt for one of these if you’ve got a significant plot of land that you need to keep tidy, but not one so large that you’d be better off going with a full-on riding mower.
How We Tested and Selected
We compiled this list based on Popular Mechanics mower testing and our knowledge of the lawn mower market at large. For our testing, we put mowers through the paces using our standard Popular Mechanics methodology: We cut turf grasses such as fescues and blue grass and rougher non-turf grasses like Timothy, clover, orchard grass, and wild oats, all in both normal and shin-deep heights. We mow uphill, downhill, and across the faces of hills. The maximum slope we cut is about 30 degrees.
That may not sound like much, but it’s about all you can do to stand on it, let alone push a mower up it or across it. We mow damp and wet grass to test general cutting performance and whether clippings accumulate on the tires. And we cut dry and dusty surfaces to see how well the bag filters under less-than-optimal conditions.
Honda HRN 216VKA
Honda mowers enjoy a sterling reputation. Having tested their walk and self-propelled mowers for the last 30 years, we feel confident that Honda’s entry level mower is a great choice for homeowners looking for power and durability. The HRN features a GCV 170 gas engine that’s built to withstand long hours of operation.
If you do your own maintenance (and most owners who buy this class of product do), you’ll appreciate the easily accessible spark plug and the fuel shutoff valve that enables better winter storage. Close the fuel shutoff and run the mower until it sputters to a halt. This will clear the carburetor of any gasoline, which will prevent the ethanol in it from disintegrating and causing running issues later on. Open the shutoff valve in the spring, add some fresh gasoline, and the mower should start easily.
All this maintenance stuff is great, but we can also tell you that our past test findings on other Hondas prove that their cut quality is outstanding for cleanliness. Sharp blades deliver a velvet-like finish. And their bagging ability is also quite good, in the same league with other well-bagging mowers from Toro.
In all, if you take mowing seriously, you should enjoy this Honda. If you have a little wiggle room in your budget, consider the Honda HRX, which features a mower powerful engine and a composite deck that won’t rust and is renowned for its durability.
One note is that Honda has announced that it will cease selling lawn mowers in the United States after this year—so if you’re considering buying one, best do it sooner rather than later.
Toro Recycler 60-Volt Max Lithium-Ion
Toro mowers have garnered more recommendations from us than any other brand for two reasons: build quality and cut quality. These were amply demonstrated in our testing as the Recycler turned in the best ratio of cut area per amp-hour of battery in the self-propelled category, while at the same time not skimping on cutting, mulching, or bagging quality.
We attribute this outstanding mower performance to three features, all upgrades to the previous version of this machine. First, the air vent at the front of the mower deck seems to improve mulching and bagging performance. Toro calls it Vortex technology, a design that increases air flow under the deck. This helps to stand the grass for a cleaner cut, which improves mulching performance, and also allows better airflow into the bag when collecting the clippings.
Next, the company’s redesigned “Atomic” blade configuration appears to assist the air flow and clipping movement. Finally, the three-phase, 60-volt motor is exceptionally efficient, resulting in a large cut area for a single battery.
Toro has maintained features that make this mower work: rear wheel drive, a one-piece deck that’s all steel (no plastic nose), 11-inch wheels to help it roll over roots and crevices, and the same fold-forward handle that was an industry breakthrough when it was introduced some years ago.
Ryobi 40-Volt Brushless Self-Propelled Mower
This is one of Ryobi’s top-of-the-line mowers, and it’s American-made construction is something we wish we saw more of. It delivers a tremendous cut area with its two 6-Ah batteries providing a total of 12-Ah of capacity, and its X-shaped blade leaves a pristine surface in its wake.
Ryobi estimates the design should provide 70 minutes of run time; we didn’t time our cut, but it strikes as plausible. Its rear-wheel drive and reasonably aggressive tire tread pattern provide good hill climbing and sidehill cutting performance, and its bagging on all surfaces (level, sidehill, and uphill) is also commendable.
Other ease-of-use features include an easily installed or removed bag that mounts and dismounts straight up and down through the handle; deck adjustment is quick and easy thanks to a single-level deck height adjustment. The straight edge deck is polypropylene; it will never rust and needs very little care other than basic cleaning.
Toro TimeMaster 30 in. Briggs Stratton Personal Pace
The Toro Timemaster 30-in. mower has been around for several years and has earned a reputation as a sturdy workhorse for homeowners who want to cut down on their mowing time. It’s also used by some professionals as well. A few years ago the Timemaster got a slightly more powerful Briggs and Stratton gas engine, so it should have no issues powering through most demanding mowing jobs.
The Timemaster is rear-wheel drive and features Toro’s Personal Pace drive system that’s used on many of its self-propelled mowers. This allows the mower to move at your speed by simply pushing down or releasing the handle, which is spring-tensioned.
With a 30-in. deck, Toro claims the Timemaster will help you reduce your mowing time by about 40% compared to using a standard-sized mower. You can mulch, back, or side discharge with the Timemaster, and the handlebar can be locked in a fully vertical position to reduce space consumption in storage.
If you have half an acre to a full acre of lawn to mow and prefer the experience of a walk-behind mower versus a tractor or zero-turn, the Timemaster is worth a look.
Craftsman mowers have been doing very well in our tests, so we can recommend this one because it’s so much like the many other of the brand’s models that we’ve tested. If you’re looking for a good blend of maneuverability and power, you’ll get it with this mower. Its front drive helps move it along and makes it easy to turn.
It’s important to note that front-drive mowers do lose some traction when running uphill, particularly with a full grass bag. But if your slope is less than 20 degrees, and you’re not bagging uphill, you’ll be fine. The side discharge will also help you handle tall grass. Adjust the two deck levers to bring the mower up to full height and have at the rough stuff.
The fact that this mower bags, mulches, and side discharges is a plus, enabling you to handle a wide range of mowing conditions, from early spring and late into the fall. Three-function mowers like this are our preference for that versatility.
Toro Super Recycler Self-Propelled Lawn Mower
This is a beauty of a mower, with a cast-aluminum deck and a smooth-running Briggs Stratton 163-cc engine. We tested the Honda engine-equipped version, and it was effective at both bagging and mulching, even in moist grass.
Equipped with rear-wheel drive and the Personal Pace system (the farther you push the drive bar, the faster the mower goes), it’s an effective hill climber and moderately effective on sidehill cutting. It has relatively small 7.5-inch tires on all four corners, which causes this Toro to bump up and down a bit on washboard surfaces. But the good news is that it’s equipped with a far higher quality tire than we’re used to seeing these days. We didn’t notice them pick up any grass on moist surfaces.
Other features we like include its forward-fold handle that has a built-in shock absorber that Toro calls a Flex Handle Suspension, and a high-quality grass bag that loads through the handle, from the top.
Are there special maintenance considerations with self-propelled mowers?
Yes. Both front- and rear-wheel drive mowers typically feature a drive belt, which can crack or wear out over time. Fortunately these belts are not difficult or particularly expensive to replace.
Secondly, you may have to replace the drive wheels occasionally. These wheels are driven with gears. there are typically teeth on the inside diameter of the drive wheel that line up with a gear on the axle. These teeth can wear out, especially if they are made of plastic. Higher-end mowers may feature drive wheels with a metal gear that meets the metal axle gear, which improves longevity of these components.
My lawnmower says I don’t ever have to change the oil, but just add oil when needed. Is this OK?
It’s not a good idea to never change the oil in your lawn mower. In a lawn mower, same as a car, oil degrades over time and is less effective at reducing heat and friction in metal components. Changing the oil in your lawn mower is easy to do and will significantly increase its service life. For most homeowners, changing the oil at the beginning or end of each mowing season should be sufficient, though there is certainly no harm in doing it more often.

What Are the Problems Caused by Bad Valve Adjustment?
Vehicle engines are precision machinery; the movement of many parts must be synchronized carefully to make the engine perform properly. Intake and exhaust valves are critical components for optimum engine performance. These valves contain mechanisms that must be adjusted correctly to allow for changes in temperature and compensate for material wear. Running a vehicle with incorrectly adjusted intake and exhaust valves can have a detrimental effect on your vehicle.
All of the intake and exhaust valves in an engine must open and close at correct intervals to allow the engine to run smoothly. These valves have a small amount of clearance between the valve itself and the mechanism that activates the valve. This clearance is called lash. If the valve lash is set incorrectly (too much clearance, or not enough), the engine may respond by running rough at idle, particularly while warming up.
Intake and exhaust valves that are not adjusted to open and close at the proper times degrade an engine’s ability to make maximum power. Intake valves control when and for how long fuel is allowed into the combustion chamber, and must be synchronized with the speed of the pistons to allow the maximum amount of mixture into the engine. Exhaust valves perform a similar function, except their purpose is to allow burnt gases to leave the engine. If the valves aren’t adjusted correctly, the engine will not burn fuel at maximum efficiency. Power and mileage then dramatically decrease.
The most serious result of incorrect valve lash adjustment is damage to the valves and related components. Setting the clearances loosely causes parts of the valve mechanism to hammer together, damaging valves and creating a knocking or rattling sound. Setting the clearances too tight can prevent valves from completely closing (or not closing for enough time), which may cause extreme heat damage and complete valve failure. Always keep your engine valves adjusted according to the manufacturer’s specifications.
