It’s always best to consult a qualified mechanic if you’re unsure about any of the steps involved. However, if you’re feeling adventurous and want to tackle. The job yourself, here’s a general guide:

Make sure you have a clean and well-lit workspace.

Adjust the idle speed. With the engine running, slowly turn the idle screw (usually located near the throttle) until the chain stops spinning. Then, turn the screw in 1/4 turn clockwise.
Adjust the low-speed mixture. Turn the L screw in slowly until the engine starts to bog down. Then, turn it out 1/4 turn counterclockwise.
Adjust the high-speed mixture. Start by turning the H screw all the way in. Then, turn it out slowly until the engine reaches its highest RPMs without bogging down.
Test and repeat. Check the chainsaw’s performance by accelerating it and cutting some wood. If it’s not running smoothly, make small adjustments to the L and H screws until you get the desired results.
