If the carburetor is new or has been rebuilt, you should set it to “factory” adjustment. You can do so by adjusting the idle mixture screws to 1.5-2 turns out, and the idle speed screw to 1-1.5 turns in. Warm the Engine Up. The engine`s running temperature directly correlates with proper air and fuel mixtures.
This method involves looking at the base of the spark plug insulator (white part of the plug) for a slight coloring on the insulator just above where the insulator comes through the steel case. If the mixture is too lean, it will leave no color, while a rich mixture will cause the fuel ring to become more prominent.

Typically, there`s a 12:1 or 15:1 ratio of air to fuel, and when there`s too much air or not enough fuel, it causes sneezing or popping sounds in the intake.

Poulin p3314 gas runs out carb
ANSWER : Set the H and L jet screws CW to stops (lightly), then CCW 1-3/4 turns each. This is a basic setting and both need to be turned CW somewhat when the engine runs. Recheck the lower chamber in the carburetor for correct installation of the needle, seat, spring, fulcrum, and diaphragm. Go to: www.drystacked.com for a detailed look at Walbro brand carburetors. Even if you do not have a Walbro carburetor, the principles are much the same. Make sure the fuel tank vent is open.

CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
There are 2 wav (sound – idle & full – not highlighted) files that I find most helpful, I think you will too. HTH

How to adjust Zama carb on poulan pro – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
ANSWER : You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won’t go any higher then turn it back in a half a turn.
