Hi First turn them(H and L) clock wise until the end and then adjust.

high speed H=3/4 turn

lowspeed L=1 1/4 turn

idle speed T adjust accordingly

Husqvarna 51 file size


Several bar and chain combinations fit the 51 model saw. If your saw runs an H46 / H80 or H81 style chain you will need a 7/32" (5.5 mm)
If you are running a H21 style chain you will need 3/16" (4.8mm)

Do I have to remove carb. on mac pro 10 chainsaw to clean needle valve


I have not seen a chain saw that must have the carb removed to remove the needle valves. The needles are nomally exposed so they can be adjusted while the saw is running. There are 2 of them.before you take them out turn them gently in till they stop counting the turns.. then pull them out and spray some carb cleaner on them and into the hole they came out of.one at a time because the tip of the needles may be differnt. then gently turn them all the way back in and turn them out the number of turns you counted.

How do i set air on husky 435 saw to fix boggy runnin


Mitch:

Adjust the fuel and air mixture screws while the saw is running... you'll find that "sweet spot"... it just takes a little patience! Small adjustments... If you over adjust and the saw quits running or starting, GENTLY turn both screws in all the way (don't damage the needle valves or seats) and turn both out one and a quarter (1 1/4) turns out. The saw should start, then adjust from there.

My husqvarna 350 chainsaw starts but wont stay running for more than a few seconds


Eric:

Find the gas/air adjustment screws on the carb (next to the the throttle cam where the throttle cable attaches. Turn the screws in all the way... GENTLY... Those are needle valves, and too much torque on them will damage the needle valve seats. turn both of them out one and a quarter to one and a half turns. Start the saw, and adjust one or the other screw in or out until the saw runs properly. If there is a plastic stop installed on the screws, remove it first, and replace it after the saw is running properly. You have to be patient while tuning the carb as it may take a while. If you adjust too much and the saw refuses to start at all, start over with the 1-1/4 to 1-1/2 turns out on the screws.

My husqvarna 178 keeps cutting out on full throttle have tried to adjust the L and H settings with no success any ideas?


As far as i remember Husqvarna never produced a model 178, however if adjusting the mixture screws does not help there is either a fuel blockage in the fuel filter in the tank ( replace filter ), or the fuel screen in the carb ( strip clean and service carb ), check the fuel hose hose for splits or cracks, asthis will greatly effect the running

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.

My chain saw will not start. I gave it to a guy who messed up the carb adjustments. Need to know the initial carb setting.


Turn both jet screws CW to stops (lightly), then back each out CCW 1-1/2 turns. This is a basic setting and should allow the engine to start and run. Start the engine and allow to warm up, then pull the throttle full on. Turn the H needle CW until the engine starts to speed up, but still 4-strokes. Correct adjustment is when the engine 4-strokes running free, but immediately 2-strokes when cutting. Release the throttle and adjust L needle so that the engine idles fairly well, but allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

When I start the motor it runs on high idle and the blade starts to spin without hitting the trigger... When I hit the trigger it sputters and turns off...


I don't know if your saw has adjustable needles on the carb, but if it does, the "low" side needle needs to be turned counterclockwise about 1/8 to 1/4 turn. THis will richen up the idle mixture which will take care of the sputtering, and should also bring down the idle speed.
