Why does my Husqvarna chainsaw bog down when I give it gas?

If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.

Why does my chainsaw stall when I give it gas?

An engine stalls when it’s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.

How do I get my chainsaw to idle?

First set the idle speed by setting it as high as possible without engaging the clutch (close to 2700 RPM if you have a tachometer). Then set the low-speed screw by turning it gently in until the engine begins to starve for fuel, then turn it out gently until the engine loads up.
