Wont Idle
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.
SOURCE: I would like to know how to adjust the carburator of McCulloch 3516 chainsaw 35cc/cm 46759-77
the carbuator has two 2 adjusting screws on it.one is high side and the other is low side.start by turnig them both in until they touch bottom.now turn them both out 1 1/2 turns.this should start and run saw.throttle saw up to full throttle and adjust high side in until you get the best RPM out of saw.do not adjust high side any less then 7/8 turn out from bottom.if you do you will burn saw up from to lean burn.once the high sie is set now adjust low side until the saw will idle by it's self.let me know if this helped you.......

Find the 2 screws. There will be a (h) high and (L) low. These are for hig rpms and low rpms. First tighten the screws. Then unscrew them about 1-1/4 turns. Then start the saw and let it warm up. Start with the high rpms first pull the trigger all the way then adjust the screw in 1/8 turns either way until it is running good at high rpms. Then work on the L rpms. Get the saw to idle then pull the trigger, there should not be any hesitation when going from L to H rpms. Just adjust the low same as the High. They have to work together so if the high is good and the low is not just right turn the h a small amount. If you have any more questions let me know

Turn the screw labled T in a little. This will raise the idle setting. Heres a link to the manual. Look on page 29 of the .pdf
