How do I adjust the idle on my Husqvarna chainsaw?
- Locate the idle-speed screw and the idle-mixture screws on the side of the chainsaw.
- Turn both the low- and high-speed screws clockwise to the midpoint.
- Adjust the low-idle screw clockwise and counterclockwise respectively, until you find the highest idling speed.
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 dies when I give it gas?
Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle. If the filter becomes clogged, not enough fuel will reach the engine for it to run properly.
How do you adjust H and L screws on a carburetor?
Set the idle speed screw(not L or H) so it is just able to idle by itself. This screw will have a “stop” it rests against. Now turn the L screw out until in decreases in rpm and then back in(very slowly) until it is at peak rpm. Adjust the H screw once more as above and it should be a very serviceable 2 stroke.
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.
Why does my chainsaw idle fast?
The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn’t really slow.
What is the T adjustment on a Husqvarna chainsaw?
The T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed. L Screw – With the chainsaw still running, take a screwdriver and turn the L screw clockwise. Next, begin to slowly turn the adjustment screw counterclockwise until you hear the engine idling smoothly.

What would cause a mower to bog down?
The most common reason why lawn mowers bog down, especially mulching mowers, is grass clippings sticking to the underside of the deck. If your mower packs in too many clippings, there’s not enough room for the clippings to cycle and the blade to keep turning. Fixing this is easy enough, it’s just a messy job.
