The undisputed market leader in agricultural tools

Husqvarna is a company that, over a long period of time, has been producing high-quality tools and equipment for gardening, and in addition its products are perfect for large-scale industrial construction.

The assortment of the manufacturer is huge, however, the main focus of the company is the production of chainsaws.

Such a model has a significant advantage, speaking specifically of low weight, which contributes to more convenient operation, and additionally similar to oil is quite economical, as the manufacturer equipped it with an engine (two-stroke) which has a small volume. Alas, not paying attention to this kind of functionality, the Husqvarna chainsaw is quite powerful. One of the most successful models is the Husqvarna 137 saw.

As for the characteristics of the chainsaw, its weight is about 4.6 kilograms, with all this, that this is the "clean" weight of the tool, without oil, fuel, not tires with a chain.

But if it is still necessary carburetor adjustment on a saw Husqvarna 137 I will try to describe this process in detail. A video on how to adjust carburetor chainsaw at idle.

Adjustment and carburetor adjustment Husqvarna 137

In the picture above, you see three screws for adjustment. Each of them has its own goal:

To adjust the idle speed, screw T is required.

Screw L is used to adjust low speed.

Screw H adjusts high speed.

Setting procedure:

First screw L (turning it), we are looking for the highest speed at idle. After we found them, you need to turn this screw a quarter of a turn against the clock. If the chain continues to rotate in this position, then we turn the screw T to stop it.

Then warm up the engine at full speed for 10-15 seconds and turn screw H a quarter against the hour. We wait 10 seconds and listen. the engine should work like a 4-stroke sound. If a squeal is heard, then the mixture is bad (we twist the screw), if the enriched mixture is smoky (tighten the screw).

After adjusting the low and high speeds, set the idle speed using the T screw. This is done as follows:

1. The engine should work

2. Turn screw T clockwise until the chain starts to rotate.

3. Turn the screw to the other side until the chain stops.

With a properly tuned carburetor, your chainsaw quickly picks up speed and sounds like 4-stroke engines.

Remember that to correctly adjust the carburetor, a chainsaw requires a tachometer and experience. Therefore, it is better to contact a specialized service!

Do-it-yourself carburetor adjustment on a chainsaw

provides efficient tool operation at full power with economical fuel consumption. Adjustment must be made with a clean fuel and air filter. For adjustment, three screws are used: for maximum and minimum speed and idle.

The H and L screws adjust the gas-air mixture ratio determined by the opening of the throttle carburetor. When the screws are loosened, the mixture is enriched, and turns accordingly fall, when twisting, the mixture is depleted. revolutions increase.

The designation H refers to the maximum speed screw that controls the main jet, L. to the minimum speed screw that controls the idle jet. With screw S, the idle speed is precisely regulated. Sometimes, to facilitate adjustment, the number of carburetor adjusting screws available is reduced.

The carburetor setting for the chain saw is divided into two steps. main (factory settings) performed when the engine is off. and the finale, released on a running hot engine. The exact angular values should be taken from the operating instructions of the particular chainsaw. If the manufacturer’s instructions are not followed, the engine may be damaged.

How to properly adjust the carburetor on a Husqvarna chainsaw

How to tune the carburetor on a chainsaw Husqvarna Adjustment carburetor on the chainsaw using three THL screws.

Basic carb adjustment.

The adjusting screws with maximum H and minimum rotation L slowly turn clockwise until they stop, then they turn 2 turns, other settings are possible

Check and adjustment of idling.

We find the largest idle speed, for this, slowly turn the screw L in different directions. After determining the maximum engine speed, turn screw L 1/4 turn counterclockwise. If the chain idles, turn screw T or (S) fully clockwise.

Check and adjust the maximum speed.

Changing the maximum number of revolutions is carried out by screw H. When it is wrapped (clockwise rotation), when turning, the revolutions increase. are decreasing. Chainsaw engines have a maximum rotation speed of 11,500 rpm. up to 15000 rpm A higher speed does not provide ignition, in addition, it becomes dangerous for the engine. The maximum speed can be determined by interruptions in the ignition. If they come, screw H is slightly turned counterclockwise.

If the engine is not tested for acceleration and maximum speed, the adjustment of the chainsaw cannot be considered complete.

When the gas trigger is pressed smoothly, the engine must quickly and confidently turn from idle to maximum (from 2800 to 11500-15000 depending on the device). If rotation is slow, delayed, screw L should turn slowly counterclockwise, but no more than 1/8 turn.

After adjusting the acceleration and maximum speed, the saw must be checked again at idle. the engine must run stably, the chain must not move. Chainsaw setting should be repeated if this condition is not met, but with the exception of the main adjustment step.

Carburetor chain adjustment

The carburetors of most chainsaws have three screws for adjustment:

L. jet screw for low speed adjustment
HOUR. high speed propeller
Screw. T from Partner and Husqvarna (near Stil Louisiana ) chainsaw adjustment idle

The H and L screws adjust the gas-air mixture ratio determined by the opening of the throttle carburetor. When the screws are loosened, the mixture is enriched, and the revolutions increase accordingly, with grinding, the mixture is depleted. revolutions are falling.

Screw T (LA) is used to adjust the idle speed. The main setup of the chainsaw is done at the factory at the end of the test. The carburetor is usually adjusted to deliver a richer (than optimal) fuel mixture. The factory setting should save the first hours of operation of the saw. Then (optional), the carburetor is tuned more precisely.

The adjustment starts with the idling set, to do this, turn the screw T (LA) counterclockwise, reaching a complete stop of the circuit with a stable engine speed.

For further fine-tuning, you need a tachometer, and it is best to trust specialists. especially since in most cases this may not be necessary.

Adjust the tool with screw L, then use screw H and end screw T (LA).

Screw H adjusts power and speed. Adjusting the carburetor to lean mixture leads to excessive speed, overheating of the engine and failure of the piston chain saw.

Warm up the engine at idle for at least 10 seconds and turn screw H 1/4 turn counterclockwise. Let the engine run for about 10 seconds. then check the maximum engine speed tachometer. If the maximum speed does not match the passport, the operation must be repeated. When the mixture is too rich, the muffler begins to smoke, when the saw is too lean, screeching and overheating.

Finish the adjustment by adjusting the idle speed, as already described above. The idle speed is set correctly if the engine runs smoothly at minimum speed and the chain does not rotate.

A carburetor can be considered adjusted if the engine accelerates quickly and sounds like a four-stroke operation with a full throttle.
