Remove the clutch cover, bar, and chain. Wash out the interior of the clutch with spray carburetor cleaner to get rid of oil build-up. Reinstall the bar, chain, and cover after cleaning the bar drive-end small oil passages that run out to the chain groove. Adjust the chain up to the bar, but not so tight that you can't move the chain by hand. Hope this helps!

The initial hi and low jet settings are in the owner's manual or sometimes stamped on the side cover next to the carburetor. If you do not have a manual go to lawnandgarden.manualsonline.com to get one.

Carb ajustment


Only Info I see is "Homelite Chain Saws" - not much to go on.
Most saws have two carb adjustment screws, Hi, and Lo.
Assuming the saw will start and run enough to warm up, then
adjust the Lo screw in, clockwise, until the motor starts to slow down,
turn only about 1/8 turn at a time. From the point where it starts to slow down, turn it out about 1/4 turn. This should give you a decent idle. Now pull the throttle, and see what happens.
A - Saw runs up to speed, but dies off, or starts to slow on it's own.
turn Hi idle screw out about 1/4 turn.
B - Saw speeds up, but runs sluggish, fat - not real hi end.
Turn Hi screw IN, about 1/8 or so, and try again, or adjust
while running at full throttle. (best way)
IF it won't run well, try turning both screws all the way in to seat them, then come back out about 1-1/2 to 2 turns. this should get you in the ballpark to set things up as above.

Once the saw is running well, adjust the idle screw to a smooth idle but slow enough that the chain stops moving.

Stay safe

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.

My Homelite ZR10926 16-Inch 33cc Ranger it is starting, idling, it dies when I accelerate it. I assume is the carburetor, maybe ? thank you.


It probably is not getting enough fuel. Check the filter in the tank. If it has been sitting with stale gass this filter plugs up.
Try running the engine with some choke. If this helps, try adjusting the carburetor high speed screw.

Can start the saw but when beginning the cut the saw power declines and will not cut. Please advise


The chain may need proper sharpening--it should not have to be forced to cut quickly. Make sure the bar and chain are being oiled enough. If the engine speed does not decline much, but the chain speed slows down, the clutch assembly may be full of oil (remove the cover and wash out the clutch with spray carburetor cleaner). Make sure the chain is properly tensioned--it should be tight to the bar, but able to be moved fairly easily by hand. Check the fuel filter and air cleaner for plugging. Make sure the fuel lines are in good condition. Hope some of this helps!

They have two separate screws? one for fast, one for slow.for the slow setting, first start the saw then screw until motor runs smooth without chain moving....if to slow the motor will stop....for fast screw....rev motor flat out then adjust so it screams its head off so to speak....it will need all its power for cutting wood so don't think you are opening it up to much as its designed for it.

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.

Idle is off??


hi leobowdy

disassembly the carb and carefully clean it.Check the air filter,the fuel line and fuel filter,check the needle,lever,small spring and the screen filter from the carb.Check the sparkplug.
high speed H=2 turns,low speed L=2 1/2 turns,adjust T
When chain saw starts adjust H,L and T accordingly.

Hi Guest,
My name is Dennis and I also have the model you are having difficulty with and I can only repeat the instructions from the owners manual (with personal comments) because they have always served me adequately 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 moveing. Adjust clockwise to increase speed. Cclockwise 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) clockwist in 1/16 a turn incriments NO MORE at a time because a twocycle needs to run at a setting foe a short time to realy prove the setting. dont run it wide open to warm it up but it should be at a fast idle. Nothing you do will be proven correct untill the engine is warm.
Good Luck
Glad to be of assistance - please rate the solution because I will learn from your rating. Thank you
Your IDLE MIXTURE may be too rich causing the engine to flood.
