SOURCE: Poulan 550 mower idle problme

Check air filter, replace if needed.
Check engine oil level and condition. Add/change as needed.
Check spark plug. Clean and re-gap if needed (.030 gap)
Drain the fuel and replace with fresh premium grade gasoline. If your local station has a notice on the pump regarding Ethanol content, drive to another station!

Most owner's manuals specify 89 octane or higher and most warranties become void if E85 fuel is used.

And finally, Oxygenated fuels are not your mower's best friend. :-)

Hope this helps.

How to adjust rich and lean settings on a husqvarna 125bv I have the tool to turn the screws

The screws are fuel screws so unscrewing them will ritchen the mixture, start with the L screw, this will be the closest to the cylinder, start the engine and warm up, gently screw the jet in, the revs will start to increase as it leans off, at the point where it then starts to die because its too lean, turn the screw out 1/4 turn, now start with the H screw, open the throttle fully, if the engine struggles to accelerate unscrew the jet 1/4 turn and try again.

How to set the high and low

Turn mixture screws completely in gently, then wind out 11/2 turns each. The saw will be able to start and run at this point. On idle wind Low clockwise till motor starts to die then anti-clockwise 3/4 turn.
High speed is a little more difficult, On full revs wind clockwise till saw starts to rev out (lean Mixture) then back till the sound starts to bubble.

Need to know how to adjust the carburator on 240 E Series Husqvarna chainsaw

There is a special tool required to turn the jet screws pt no. 530035560 the screws are marked L and H you need to turn the L screw only this will adjust the mixture at idle, anto clockwise will increase the mixture, the third screw on the carb is to increase the idle speed once the mixture is correct, this can be adjusted with a cross cut screw driver.

Carburetor setting for Husqvarna 372xp chainsaw

The jet screws are fuel not air screws, the more they are unscrewd the richer the mixture becomes, basic settings are one and a quarter on the L screw and one turn on the H screw, you will have to fine tune from there, idle speed should be around 3000rpm, and max speed should not exceed 13000rpm, this should be set with a suitable engine tacho, when fine tuning always start with the L screw first, start gently screwing it in, the revs will start to increase as it leans off, when it starts to die because its too lean, unscrew until the revs pick up again, as you keep unscrewing you will hear the revs start to drop because it is becoming richer, leave it there, now blip the throttle, it should pick up instantly, if not turn the screw out a further 1/8 of a turn, the H screw is like a govener the more you screw it in the faster it revs, so do not exceed the 13000 rpm or this is a good chance it could seize, before any adjustments the fuel filter in the tank should be clean or replaced, the air filter should be cleaned and fresh fuel should be used.

Jet adjustment

The carb has an L screw, an H screw and an idle screw, both screws are fuel, not air screws, the L screw will increase the fuel mixture from idle to half throttle, the H screw will increase the fuel mixture at full revs, this will also govern the maximum revs the saw will do, it is very important you do not exceed the manufacturers recommended max rpm, if the saw will not rev clean up throught the revs, increase the L screw bit at a time until it does.

Need instruction on how to adjust carberator

Adjusting carbs on chainsaws is not to be taken on lightly, there will normally be three screws, an L screw, an H screw, and an idle scre, the L screw will increase the fuel mixture from idle to half throttle ( they are fuel screws not air screws ) the H screw will adjust from half throttle to maximum revs, start with a base setting of between one turn and one and a half turns out, start the saw and warm through, allow it to idle, if need be increase the idle screw to get an idle, turn the L screw in slowley, the revs will increase as the mixture leans off, it will reach a point where it starts to die, now back it off a quarter of a turn, blip the throttle, the saw should pick up clean, if it has a flat spot increase the L screw slightley, now set the idle so it idles without the chain moving on the bar, now screw the H screw in to get full revs, be aware this should be set with an engine rev counter, do not exceed the manufacturersmax revs, hobby saws normally run at about 12500 rpm with an idle speed of 3000 rpm.

I need to tune up my saw but I can't find my owner's manual. It won't idle. Need to know how to adjust the low speed. It runs well but my low speed idle won't adjust to make it keep running.

The theory is much the same on all chainsaw carbs, start and warm the machine up, increase the idle speed with the idle screw if it will not tick over, start to turn the L screw in, the revs will increase as the mixture leans off, it will reach a point where it is too lean and start to die, at that point turn the screw out 1/4 turn, check it revs up clean, if not turn screw out bit at a time until it does, now set the idle speed with the idle screw. Before attempting this make sure the fuel filter is clean, and also the air filter.

Hi, i have a 1999 husqvarna 254xp... its abit hard to start and never idles more than 3secs.....from doing some looking into , i think maybe the L screw needs adj? if so could u explain in simple terms how...

In simple terms here we go, turn both L screw and H screw fully in until they stop ( clock wise ) now turn the L scew out one and a half turns out, and the H screw one and a quarter turns out, start the saw ans warm up the engine, allow the saw to idle, if need be turn the idle screw in to gain a slightly fast idle, start to turn the L screw in, the revs will start to increse as the mixture leans off, thet will reach a point where the engine then starts to die because it is too len, at this point unscrew the screw quarter turn, check the machine revs up clean, if there is a hesitation unscrew the jet a smaal bit at a time until it revs clean, now adjust the idle screw so the engine idles without the cutting chain rotating around the bar, the H screw should be about right however if it sounds too rich at full throttle srew the jet in a small amount until it sounds right, the maximum rpm should not exceed 13500, this should realy be check with a rev counter, if the engine revs too high there is a fear that it will over heat and seize.

How to adjust idle on 94 eclipse

you should be able to adjust it by the trottle cable check under the hood and see if theres not two nuts holding your trottle cable in place if so ajust if need be. this is a easier way to increase your rpm at idle but you shouldnt be able to decre your rpms at idle this way. for that yu may have to look and see if there is a adjustment screw on your trottlebody that can increase and decrease your rpm at idle. if your have a low idle problem try cleaning the inside of your trottle body really good with a lint free rag and some trottle body cleaner also try cleaning your idle control vavle if cleaning your trottlebody didnt help.

On my gsxr 750 l (1990) when doing about 30 mph@3000rpm the revs are up and down, almost mis-firing, have removed,cleaned and balanced carbs but problem still there. any ideas?

Check the color of the spark plugs.
If they are totally clean, your mixture is a little to lean.
To richen the mixture at the half-way trottle, raise the fuel level in the carbs.
At closed or less than 1/4 open trottle, set with the mixture idle screws.
Check also the rubbers between carbs and cilinder head. They must be 200% air-tight!
