Where are the screws on carburator for my chain saw

A good starting point would be about 1 to 11/4 turns out from the screws turn all the way in. Take note of the turns required on each screw to turn in (clockwise) This does not apply to the idle adjustment screw.

Walter:

gently run the fuel and air mixture screws on the carburetor all the way closed (clockwise).then turn them out one and a quarter turns each. That setting should allow the saw to start if you are getting fuel to the carburetor. Once the saw starts, make fine adjustments to the fuel/air mixture screws until the saw runs to your satisfaction.

Hi

If its an old Homelite you should have 3 screw on the carburator.
First bigger screw for adjust idle on the butterfly.
The 2 other for the mixture. One screw is ''L'' for low rpm mixture an other screw is ''H'' for high rpm mixture.

First the idle screw. It should just open a little bit the carburator butterfly.
Second full close both ''L'' and ''H'' screws (turn clockwise).
After open both ''L'' and ''H'' screws 1/2 to 3/4 turn (conterclockwise)

Normally the saw should start. Tune the ''L'' screw to have the motor running at idle if idle is to fast at this point is not important. After motor is running by itself at idle tune the ''H'' screw.
Full throttle tune the ''H'' screw to be able to pass from low rpm to high rpm with no lag.
Than at full throttle open again a little bit the ''H'' screw to make the high rmp mixture more rich.
Becarful if ''H'' screw is not adjust correctly the mixture will be to poor and motor damage can occur.

It may be necessary to re-tune a very little bit the ''L'' screw and idle screw after the correct setting of the ''H'' screw.

If it still not working carburator kit may be needed,

On some newer model there is no adjusting screws in this case see if a carburator kit is available for your model.

Basic settings can vary from model to model, a good starting point for most carbs is screw both H and L screw right in ,then back the H screw out 1 turn and the L screw 1 and1/4 turns, the machine should run well enough to fine adjust from there, they are both fuel screws, so the more you unscrew them the richer the saw becomes, always remember if there in another under lying problem adjusting the carb screws will not always help, before any adjustment clean or replace the fuel filter in the fuel tank.

Turn both jets all the way in.then turn them out 11/4 turns out.start it up and you can fine tune it from there by turning the jets in or out.

your carburator is gummed up. Get some carb. cleaner additive for your fuel, run a couple of tanks of treated fuel through the saw and it will be ok.

You may have the one that uses splined adjustment screws rather then limiters.If you do you can order this from your husky dealer.You can tell if you have limiter caps by shining a light through the screw hole and see if caps are white or red.If black you have round splined needle ends that take a hard to get adjustment tool.

they should both be 1 1/2 turns out from bottom to get you started. Make sure your spark plug is clean and dry first. Good luck

you need to adjust the gas an air on those two little screws on the carburator
