Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor fasteners are tight. If no help, then if the H and L jet screws have slotted heads, turn the H jet needle CCW about 1/8 turn until the engine 4-strokes at full throttle, but immediately 2-strokes when cutting. If the jet needles have 'D' heads, then you are stuck taking the saw to a servicing dealer to get the carburetor adjusted as only they are authorized to have the necessary screwdriver. (Thanks to the EPA for saving us from this serious pollution problem) Hope this helps!

Chokes and Dies when cutting


Adjust the choke or carburetor. In case your chainsaw stalls when the engine is idling, ensure that the choke is set properly. To do so, first try releasing it to adjust it, and then move the plate and tighten all screws once again. To loosen any grit, spray carburetor cleaner spray on the choke's shaft. The carburetor may also need to be adjusted; consult your owner's manual which will guide you on resetting the idle mix screw.

Husqvarna starts but cuts out if not on full throttle


There is a screw that allows you to set the Idling. Take the top off so you can see the carb. Without starting it play with the throttle trigger you will see a shaft move in the carb, the shaft will probably have some small attachments on it. Identify the screw that acts as an "end stop" when the throttle trigger is released. Once you have found the idle screw you can start the machine and turn the screw in slightly. Set it so that the machine idles but not too fast or the cutting chain will start running.

Chainsaw starts normally idles well increase speed and cut a log then decrease speed and the motor stops


Have you tried changing the gas you are using? Sometimes with the addition of ethanol, water condensation is attracted and builds up in the system, creating a fuel mix that affects performance. Also, make sure your settings for High speed throttle are correct. You may need to make a small adjustment on the screw marked H for running high throttle.

How do u set the darb screws on a mac cat 839 chainsaw


Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. Start the engine and allow to warm up. Open the throttle and adjust the H jet needle CW until the engine starts to speed up. Correct adjustment is when the engine 4-strokes at speed unloaded, but 2-strokes immediately when cutting. Release the throttle and adjust the L jet screw CW for better idle, yet allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the engine continues to run, but the chain doesn't try to turn. Hope this helps!

How do I adjust the carburetor on a Poulan 38cc chainsaw? Someone has messed with the low and high adjustment


Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Be sure to check the fuel filter, air cleaner, and muffler for plugging. Start the engine and allow to warm up--pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is reached when the engine 4-strokes at speed, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but will allow the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

My poulan 360a chainsaw cuts out when used for 5 mins. when opening throttle to saw woods it does not respond and cuts out.it starts again ok but will not respond to throttle. it is ok when motor is cold.


Check the fuel filter for plugging, the fuel lines for hardness/cracking/splitting. Clean or replace the air filter. Clean the muffler if plugged. Make sure that the carburetor fasteners are tight. Check the spark plug condition--gap should be 0.020" and the insulator should be light to medium tan color. If still having problems, the carburetor may need to be cleaned and serviced. Hope this helps!

POULAN TRIGGER PROBLEM


Remove the air cleaner which usually exposes the carburetor--operate the throttle (engine off) and watch what moves--likely wood chips blocking the action--less likely, a wire linkage got bent somehow, or there is sawdust in the trigger mechanism. From your description, this saw starts full-throttle at the get-go. Sort of dangerous!
