Hi 1tgriffin,
My name is Dennis and I hope that will serve your needs.
IDLE ADJUSTMENTS:
There are three adjustment screws on the carburetor labeled
H (for High speed MIXTURE)
L (for low speed MIXTURE)
T (for idle SPEED SETTING)
They are located just above the primer bulb. If your saw floods so soon in the starting process the idle mixture setting can be set too rich and the speed may be set too slow. Remember the chain will not move when the idle speed is set correctly with a WARM ENGINE!
Adjust the idle speed to just below chain movement WITH A WARM ENGINE this is just below the activation RPM of the centrifugal clutch. Let the engine run at a higher speed than idle until it is warm -- 3 min -- you may have to keep goosing it until then.
Please don't exceed the limits of the plastic limiters when making adjustments.
If you haven't adjusted the mixture screws you may just have to adjust the idle speed and that can start my turning that screw all the way in to the stop and then back out 4-1/2 turns for a good place to start. FAST IDLE -- Adjust the speed until the engine runs with out the chain moving. Adjust clockwise to increase speed. C clockwise to decrease engine speed.
Accelerate the engine and if it stumbles and makes too much smoke it's too rich turn the
LOW SPEED MIXTURE (in) clockwise in 1/16 a turn increments NO MORE at a time because a two cycle needs to run at a setting for a short time to really prove the setting. don’t run it wide open to warm it up but it should be at a fast idle. Nothing you do will be proven correct until the engine is warm.
Good Luck
Glad to be of assistance - please rate the solution because I will learn from your rating. Thank you

How to adjut the carb


This is tricky because it's one of those hands on things to show & hear. Most homeowners get this wrong and either the saw runs to rich or too lean(real danger). On the high speed jet, you turn it IN until the saw seems to scream uncontrollably(just for a few secs!) and then back the screw out until it starts to 'four stoke'....which means its cutting out slightly. On the low speed jet, you adjust right at the point where blipping the throttle trigger gives you fastest response. But if turning IN the low speed jet is raising your idle significantly, then you've gone too far.
If you've got the high speed jet set correctly, it will four stoke until you bury the bar and then smooth out perfectly under load.

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.

Poulan 45cc chainsaw will start running with starting with choke, but will not stay running.


Sounds like the low speed fuel adjustment is out of whack....you can reset it by turning it in all the way clockwise...then as a starting point, turn it out 1 and 1/2 times, start the engine and slowly adjust the screw until the engine starts to choke out..when this occurs, turn it back in until it starts to choke again...then you need to set it somewhere in between to find the "happy medium"....thew high speed screw is adjusted after you get the engine idling properly...if you haven't messed with this then I wouldn't worry about it..unless you have poor high speed operation, then you will need to set the high speed screw...the object here is to obtain the best low to high speed throttle...if , when you throttle up the saw, the engine bogs or goes to high speed slowly , here is where you adjust to get the best throttle response...use small increments until you achieve the desired response

How do I adjust the carburetor on a Poulan 38cc chainsaw? Someone has messed with the low and high adjustment


Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Be sure to check the fuel filter, air cleaner, and muffler for plugging. Start the engine and allow to warm up--pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is reached when the engine 4-strokes at speed, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but will allow the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

Carb rpl and adjustment


you have 2 screws marked H and L. With the engine running, turn the L (low) screw for best idle. Then for the H (high) screw, Hold at full throttle, turn screw, and listen for smothest and fastest revs.

After running for about a half hour or so it begins to stall in between cuts . . should i adjust the low,high or idle screw


Is the chain being properly oiled? You should get a thin line of oil after running the tip of the saw near to a piece of paper or cardboard for moment or two. Is the saw getting overly hot after running? Clean the cylinder and air passages with compressed air if it is. Check the muffler for any plugging of spark arrestor screen. Turn both jet screws CW to stops (lightly) then turn both out 1-1/2 turns CCW for a basic setting. Pull throttle full on (after warm up) and adjust H for high engine speed, but 4-stroking that smooths out immediately when cutting. Release throttle and adjust L for fairly smooth idle, but rich enough to allow the engine to 'follow-the-throttle'. Adjust idle speed so that the chain stops moving. Hope this helps.

"L" adjustment screw on the carburator


L is for idle speed mixture and H is for full throttle mixture. Adjust H, when engine is warmed up, with full throttle--adjust for high speed, but 4-stroking which should smooth out just as soon as you start cutting. Allow to idle and adjust L for smooth idle, but rich enough to allow the engine to 'follow the throttle'. Set idle speed screw to just allow the chain to stop moving.

I have a poulan 2150 chainsaw and the chain never stops spinning. how do i adjust it to stop spinning when i am not cutting?


Firstly consult your manual regarding carburettor settings. There should be a high and low speed adjustment on the saw, often called or labeled as "L" and "H".

These are often located on the main motor body, closer to the handle on one side and require a screwdriver or similar to adjust. They might be buried and you have to look down the adjustment holes in the outer body to see the screws.

Basically you need to adjust the "L" or low idle screw.

Firstly, warm up the chainsaw and allow it to get up to temperature... The blade, as you say will probably be spinning still with hands off the throttle... Grab your screwdriver and adjust the "L" or low idle screw turning it counter-clockwise (at least on most saws) very slowly until the chain just stops turning on the bar. If you go to far you may stall the motor. You just want the chain to have just stopped moving on the bar, and that is your "L" setting position...

Has to be done with a warm engine though.

Need high and low ajustment procedure


Hi carlayoung

Start the engine and turn the high speed screw "H" in(clockwise)until the engine starts to slow down(the fuel mixture is to lean,not enough gas).

Slowly turn the screw out(counterclockwise)until the engine begins to run smoothly,keep going very slowly until the engines just begins to run rough again(rich condition,watch for black smoke from exhaust).

Then turn the screw in again(clockwise) to a point about half way between lean and rich condition.This is the properly setting.

The low speed screw"L" adjust in the same manner.

The idle speed "T"adjust accordingly.
