Member Discussion on Husqvarna 240e Chainsaw Idle Adjustment I have a new 240e and cannot keep it running. It will start, after many pulls, and one of two things happens. After running for 30 seconds, I will tap the trigger to set the idle and it will promptly idle down and die. Or, I do nothing, and it will idle for a bit and die. Restarts are difficult. I did not get a manual with the saw, so all I have to work with is one I downloaded. Idle adjustment is mentioned, but no indication where this adjustment might be. Thanks

You have asked a vehicle based question in a Chainsaw category. Please try again.

Remove the handles, then remove four 8MM bolts from the bottom securing the engine case. The entire assembly will then rotate upward,
allowing you to remove the two 8MM nuts and carburetor.

The symptoms indicate lean running, so check the fuel filter for plugging and the fuel lines for decay or other damage. Husky seems be having troubles with our ethanol treated fuel and may require some warranty attention. We have a year old 435 Husky that would not start after about 3 days of excellent running--warranty replaced the carburetor which seems to have us working well now. Good luck!

That seems low to me. Page 15 in your manual is the only oil discussion I found. Usually there is an oil pump adjustment reference somewhere. I didn't see one beyond return it for service on page 15. Are the chain and bar hot after cutting a while? I recommend you not get a longer bar without an oiler adjustment. I think the hand of the EPA has been here.

An IPL (exploded parts list) for a 440 can be found here:

There is no oiler adjuster listed. HTH

Might be a good idea to copy the IPL,

Read the warm start procedure from the operators manual.
1. Pull choke (sets fast idle)
2. Push in choke (fast idle retained)
3. Make sure ignition is on, pull (usually once on my saw)
4. Advance throttle slightly to release fast idle.
I made the mistake ONCE of not setting the fast idle. My shoulder gets sore thinking about it. HTH

Preset both needles about 1-1/2 to 2 turns CCW from CW stop. Set H needle first after warm-up. At high speed, engine should 4-stroke with no load, but smooth out with light load(cutting wood). Set idle speed so that it will keep running, then adjust L needle so that engine tries to follow the throttle, but idles fairly smoothly. Readjust idle speed so that the clutch is not trying to drive the chain.

Most chainsaws and small engines are 1.5 turns out.

You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

Find the 2 screws. There will be a (h) high and (L) low. These are for hig rpms and low rpms. First tighten the screws. Then unscrew them about 1-1/4 turns. Then start the saw and let it warm up. Start with the high rpms first pull the trigger all the way then adjust the screw in 1/8 turns either way until it is running good at high rpms. Then work on the L rpms. Get the saw to idle then pull the trigger, there should not be any hesitation when going from L to H rpms. Just adjust the low same as the High. They have to work together so if the high is good and the low is not just right turn the h a small amount. If you have any more questions let me know

Try adjusting the idle. The will be a couple adjustment screws, there will be an (H) and (L) you will need to turn the (L) First tighten the sdcrew completely then turn it 1-1/4 turns. This will be a good to start. Then just turn it small amounts until you get it to idle. Also there should be an idle adjustment you can adjust.

The carb needs to be adjusted. Look for 2 adjustments label High(H) and Low(L). Low is the one that you want. Start you chainsaw and let it warm up and turn the L adjustment a until you are able to let it idle on its own. Hope this helps.
