The gasoline generator does not start the carburetor shoots. Checking the fuel supply

Why does not the gasoline generator start??

Over time, even the most reliable and high-quality equipment can fail (does not start gasoline generator causes). The gasoline generator is not an exception. The reasons for this can be many. Most owners begin to panic and seek help from specialists, but in fact some problems can be solved independently, so to say, in the home. In this article, we will tell you what the causes may be due to what does not start the gasoline power station, and how this can be done.

There may be several reasons why the gasoline generator does not start. So, let us consider the possible reasons why the gasoline generator does not start at all, or why, when it starts, it immediately “stops”. The three main components that keep a carburetor engine running are gasoline, air, and spark. You have probably already guessed that we need to check these three devices, which are necessary for the proper operation of the engine.

The owner of the gasoline generator can incorrectly calculate the required amount of fuel or just forget to fill the fuel tank. First, you need to check the path (through which the fuel is fed to the carburetor). Secondly, the mix of petrol may be outdated, i.e. it has lost its octane properties What you can do? Pour a fresh mixture into the fuel tank and try to start the generator again.

It is important to remember that on the pipe under the gas tank there is a tap. So, you need to carefully monitor that it is open.

It is necessary to check whether it leaks? If it’s leaking or broken, replace it.

Maybe the alternator won’t start because there’s no spark.

What to do? To begin with it is necessary to unscrew the plug, check its condition, the presence of spark, replace it with a new one if necessary. If the spark plug has been in the fuel mixture, it should be unscrewed and dried. Soot on the spark plug. clean it with an awl or a needle, clean the electrodes with sandpaper. If there is heavy soot, replace with a new one. A dry spark plug means that there is a problem with fuel supply to the cylinder. If you get a spark and the alternator won’t start, there is most likely no fuel in the carburetor. The oil sensor could be stuck as another reason for no spark.

if there is no spark, pay attention to the oil level sensor

The following is the possible cause of why the alternator does not start. it might be a dirty air filter. An unclean filter is blocking the flow of air needed for combustion. What you can do? Take it off, rinse or thoroughly clean and dry it out then put it back. Important thing to remember! When starting the unit, the air damper should be in the “closed” position.

If the engine fails to start, check the fuel system.

Causes of fuel system malfunctions:. Fuel is not flowing into the float chamber;. the fuel has lost its properties over time. What can be done? 1. Find the drain screw on the float chamber of the carburetor, 2. Then use a small container to drain some fuel from the float chamber. 3. check that the fuel is getting to the float chamber.

If none of the above has not helped, you should contact an experienced professional in our service center by phone: 063 202-90-70 097 023-42-42. Most likely the cause of your gasoline generator malfunction is in the carburetor, and this is the work of professionals. Our specialists can pinpoint the cause of the malfunction and repair it within a short period of time.

How to Perform the Proper Startup Procedure 1. You must first turn on the alternator, with the key or button in the “ON” position; 2. Then open the top tap; 3. Close the choke on the carburettor; 4. It is necessary to sharply (a prerequisite), pull the hand starter or the electric starter.

We can conclude that if you monitor the cleanliness of the air filter and spark plugs, do not start the power plant under load, close the air damper of the generator, leave the fuel tap open, then these simple rules will allow you to extend the life of your gasoline generator.

Start of the generator in winter

The main difference between running a gasoline generator in winter are the climatic conditions, which dictate certain rules. In order to start the gasoline engine without problems in cold weather, it is necessary to follow a certain set of recommendations:

  • Before start-up it is necessary to check the oil level. When operating in winter, special attention should be paid to the quality of the engine oil;
  • The same conditions apply to gasoline. Using unleaded fuel is preferable because it is more suitable for low temperatures;
  • it is obligatory to start the unit at zero load.

Starting a generator after preservation

Actually, this operation is carried out, as well as normal starting, only the preparatory stage deserves separate attention:

  • before starting the engine oil and install a new oil filter recommended by the manufacturer;
  • install a charged battery;
  • fill up the generator with fuel.

Any equipment begins to malfunction over time. This can happen for a variety of reasons. A gasoline generator can also stall, a diesel unit can stop working.

gasoline, generator, does, start

Gasoline generator is a device, which converts heat energy into electricity. A machine consists of two main parts. the engine and the generator. The engine drives the shaft of the generator, which delivers a certain voltage.

The Reasons Why the Oil Gets into the Air Filter

Oil in the air filter is a sign of serious engine problems. The causes of this phenomenon can be: damage to key engine components, clogging of the oil drain, significant wear or mechanical damage to the rings, severe clogging of the air filter itself.

Most of the problems that arise during the operation of a gasoline generator can only be handled by a specialist with the required knowledge, experience, skills.

Elimination of the main malfunctions of the gasoline generator by your own efforts

The basic principle of repairing any machinery, is to troubleshoot by eliminating. How we do it. The generator comes to us and we begin to check it:

  • The first thing to inspect the exterior for mechanical damage and oil leaks, as well as the presence of rust in the tank. Next, check for oil and crank the engine with the starter (see compression resistance and extraneous noises). Let’s try to start it.
  • If it doesn’t help, check the ignition switch or ignition switch. Immediately take a new spark plug (leaning the plug on the ground, crank the engine), if there is no spark or it is weak, try to disconnect the wires from the oil sensor relay and replace the spark plug cap. If it didn’t help check ignition switch or ignition button. If everything is fine there, it means that the ignition coil is defective.
  • If there is a spark, try to start the engine. If it starts and stalls or operates with the choke closed, the carburetor is definitely clogged. Many people say they cleaned themselves, but the symptoms are the same. It is obvious, carburetor should be cleaned by disassembling it to a bolt, with special cleaners. And it is half of the deal, further it is necessary to establish it and correctly adjust pulls and springs of a flap and a regulator. If it does not start at all, add some gasoline in the combustion chamber through the spark plug hole or open the carburetor choke.
  • Rust in the tank is a very unpleasant problem, you can clean the fuel system and everything will work. But, soon, after some time, this rust will get into the carburetor (in the jets, under the needle) and the symptoms will repeat. If there is rust in the tank, it is almost impossible to remove. It is possible to pour special solvent into the tank overnight or install a fuel filter, but the only salvation is to change the tank.

Alternator Filters

Many people know that the alternator in the fuel system has filters, which become dirty during the operation Fuel and oil or air filter screens should be cleaned of dirt and changed periodically. If the filters get dirty the alternator will malfunction, stall and overheat.

Fuel for refueling must be of good quality, at least Ai-92 grade. A complete oil change should be done every season, and the consumable level should be checked before each start-up of the generator.

Excessive heating of the engine

Low voltage caused by capacitors

An alternator can start to stall if the capacitors are burned out, the brushes are worn or there is poor contact. The problem can be solved by complete disassembly of the generator and a thorough inspection of all parts and components. It is better to entrust such work to a specialist.

Also failure of carburetor, piston system and speed regulator can be the reason. These problems are solved by diagnostics and repair.

What the kettle can do?

Thus, in this article we have reviewed what a user of a generator without special knowledge on repair can do, if it does not start the generator. Naturally, these actions can be applied to any machine that has a gasoline engine.

Frequency of maintenance

To find out why a gasoline generator does not start, it is necessary to perform a complete diagnostics. It will last a long time without malfunctioning or breakdowns if you follow the schedule of maintenance intervals:

The part Need to be checked or cleaned When to Replace
Oil It is checked before the first and subsequent start-ups Oil must be changed every 50 hours of operation and functioning of alternator
Air filter It tends to get clogged. It must be checked each time before startup. If clogged, need to be cleaned and flushed Air filter change when completely worn
Spark plugs They also fail if not properly maintained. If defective, unit will not start Checked every 100 hours of continuous operation
Fuel Hose This is a rubber tube that is made of elastic material Must be replaced if deformed or cracked. The average life span is about 3 years

The generator starts quickly and easily. But to ensure correct operation it is necessary to check the oil level every time. To check oil level, you need to get to the oil dipstick cover. There are special divisions on it for a quick check. You need to unscrew the cap and check the oil level. If it is not enough, then make a top up. The oil must be of the same composition.

Problems with the internal combustion engine.

Problems in the operation of the generator are usually due to a lack of voltage, arising from a variety of causes. It can be lack of contact, defective brushes, burnout of capacitors, PWM blocks, etc.п. If the voltage jumps with constant engine speed, it is most likely that the problem is in the field regulators. You must disassemble the machine to find out the exact cause of its failure.

gasoline, generator, does, start

Difficulty starting the engine is usually a sign of engine malfunction. Timely detection of the cause. means to prevent its further development and stop the negative impact on the operation of the unit.

Often the cause of failure are several interrelated factors. In this case, they have to be eliminated comprehensively.

The most common circumstances preventing normal engine starting are:

Poorly working ignition system. The following options are possible here:

  • Problems with the spark plug: too big or too small distance between the electrodes (you need to position the electrodes at the optimal distance), a violation of the insulation (replacement with a new spark plug will help), heavy soot formation (requires thorough cleaning of the plug);
  • Problems with the ignition coil: violation of insulation or torn winding (must be replaced), incorrect connection of circuit elements or malfunction (if it is impossible to fix the faulty circuit, you must replace it).
  • Lack of fuel in the tank (it is necessary to fill the tank);
  • Fuel hose clogged or jammed (thorough cleaning or complete replacement of the hose is needed);
  • Air trapped in fuel hose (check tightness of connections, retighten if necessary);
  • Gasoline of poor quality or diluted with water (pour more quality fuel);
  • Problems with carburetor: breakage, fuel or debris in carburetor. The problem will be solved by disassembling and cleaning the carburetor. The problem may also be caused by improperly installed throttle valve, which can be solved by careful adjustment of this part.
  • Badly tightened bolts fixing the cylinder head (tighten more tightly)
  • Worn piston, piston rings, or cylinder (repair or complete replacement required)
  • Poor contact between the working chamfers and seats (repairs needed)
  • Stuck valve (needs to be repaired)
  • Gap between the valves, the value of which differs from the gap value provided for this model (the gap value must be carefully adjusted);
  • The inlet manifold gasket does not prevent the passage of air (tighten the screws; if the air continues to pass, the gasket must be replaced)
  • Spark plug not tightened properly (tighten plug more)

The engine does not reach the declared capacity

Excessive engine heat

  • The value of the gap in the valves differs from the one set for this model (the gap must be adjusted)
  • Valves not tightly closed (Adjust tightness of valve closure)
  • Excessive clearance between valve guide sleeve and valve spindle (replace valve)

The gasoline generator does not start for some reason

Every owner of a gasoline generator faced the problem when the generator, which has worked properly up to now or just purchased, does not start or starts and immediately stops.

What to do in this situation? Where to go?

In many cases, to find the reason why the gasoline generator does not start, you can find and fix it yourself.

Quite often the problem that customers have in the service center is insufficient oil level.

Keep in mind! You run the risk of overpaying for a gasoline generator repair if you try to save on oil or gasoline. Using low quality gasoline almost always causes clogging of carburettor and fuel filter.

PETROL, AIR and SPARK. The main components on which the work of the internal carburetor engine is based on which the work of the internal combustion gasoline carburetor engine is based on.

So, a gasoline generator is filled with fuel, the battery is connected, the ignition key is turned, but in response is complete silencethe starter turns once or does not turn at all.What to do in this case?

gasoline, generator, does, start

step 1. check the battery

The car battery is suitable, of course its size is different from the battery on the alternator, but both are 12 volts.

Starter turns perfectly, replaced the battery, but gasoline generator does not start. What to do?

step 2. check oil in the engine crankcase and fuel supply

Gasoline is coming in, battery is in good condition, BUT gasoline generator won’t start.

Step 3. contaminated air filter

What to do if the air filter is dirty?

The air damper should be in the “closed” position.

How to check if the spark plug is working?

Important! Only hold the candle by its ceramic insulator. it is dangerous to touch other parts (live candle).

5 step. check for outdated fuel

One of the possible reasons your alternator won’t start is because the fuel is leaking. 6 months Over time, the fuel loses its octane properties. drain and replace with new.

If the alternator has been out of action for a long time. jets and carburetor could be clogged, it is necessary to make cleaning of the carburetor with a special equipment.

This is a list of basic generator problems that you can identify and fix yourself. In other cases we recommend to contact us at “Rem Tech Service”. Or if the above actions were not successful, please call us on: 063 202-90-70 097 023-42-42.
