This is likely to be a problem on the air inlet side of things. It would help if you had given the model number then a specific answer could be given. However, check the inlet manifold (the bit between the carb and the engine. It is likely there is a leak in that. Often they are made of a rubber like substance which goes hard over time. If the anti-vibe springs or rubbers need renewing then sometimes the engine will wobble about against the carb and the increased vibration causes splits in the inlet manifold especially if it has hardened. Hope this helps.

There are two idle screws one high, and one low. Your high adjustment idle screw needs to be adjusted.

SOURCE: chainsaw starts works for about a minute two

That is the sign of out of fuel, Mine races when it runs out, you must have a clogged up fuel line, Take off the back cover, get the fuel line off at the carb and blow through it. Peek inside the fuel tank and see if there is anything floating around.

What are the air and gas settings for a poulan micro XXV chain saw


adjust the L screw in fully till right in,then out 1.5 turns,same with H screw.Then start saw,adjust L screw in or out slowly till you get max revs.You may need to lower idle via idle screw if revs too high.When screw cant acheive better revs,reset idle.Then,rev saw to max revs,adjusting H screw to get max revs,then when max revs acheived,turn screw anti clockwise 1/4 turn out.That gives it enough petrol to cool the tip of the plug

My remington electric chainsaw 3.0 is not cutting and making a high pitch screech when i go to cut with it


Hello. Please make sure the saw brake is not set. This locks the blade so it cannot spin. If it is locked then if you try to rev the saw, the blade cannot turn and the clutch will scream. The other thing it could be is it sounds like the chain is out of the groove and the clutch is slipping BAD. UNPLUG the chainsaw. Check to make sure the chain turns freely around the cutter bar. If it does not move at all, you will need to closely examine the cutter bar to see if it has 'popped' out of the guide path. You must also make sure the chain is on the drive gear correctly.
These are 2 things to look at that can help you. Hope this helps..

Got a stihl hs75 starts and runs up to 3/4 revs but cuts out on full revs what could be the problem?


Hi, basically its starving for fuel in the upper revs. Check the fuel hose between the tank and carby, they are prone to perishing. If ok it may just need the high speed screw backing out a bit. Regards Phil.

42cc 18 inch craftsman chainsaw model 358-351910-18. Saw runs great at idle or while not cutting wood, when starting to cut wood just after the entire bar gets into the wood engine bogs down and chain...


Generally this is a fuel / air ratio problem. Usually it can be solved by a carb adjustment. On the carb there are usually two screws, one marked low or L , the other marked high or H. Low is your adjustment for idle mixture, high is for mixture at full throttle. The saw should Always be adjusted to run well during the cut. Make adjustments a little at a time, then try The saw. Continue small adjustments untill the saw is performing well at full throttle while Cutting.

The chain saw runs okay until i start to cut wood on higher revs then it cuts ouy


Does it run O.K. with high revs. with no load, but dies when you start to cut (load) ? If that is the case your carb. needs to be adjusted and that is difficult to put into words. Without knowing what make of carb you have because they can change from year to year, and also depends on the model. Without knowing make of carb I suggest you try to turn the L (low) and H (high) needles in (clockwise) until they are lightly seated so you don't damage the needle or seat. Now turn them both out (counterclockwise) one turn as a start. Start your saw to let it warm up now rev it up it should not hesitate or run rough while reving up. If it does turn low needle out 1/4 turn or more if needed until it does not hesitate. (turning any needle out will let in more gas turning in less gas) If you get this far good idling and reving up, now adjust high needle the same way. With high needle you can also try turning it in. keep on adjusting needles in or out in small increments until it runs right. If you cannot get it running right after all this, you probably need a carb overhaul, just a cleaning or carb kit if diaphrams are stiff or damaged. I hope this helps you. Please forgive grammar errors. Let me know how you made out.

Cuts out on high revs 240 chain saw


Many saws made today are using electronics for engine control. If the engine rpm's starts to rev to high, the electronics in the coil will start to 'cut out' some of the spark. This is normal in this senerio.

But, now the real problem causing the senerio;

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb
