Question about Poulan Pro Chain Saw 46cc 20"
Many chainsaws have the fuel tank mounted very close to the engine cylinder. In the process of filling the tank over and over a lot of mixed gas is spilled and some of it runs down on the cylinder head. Being mixed gas and having oil in it, it leaves an oily residue. This oil will seem to collect a massive amount of sawdust over time. The sawdust coating the cylinder causes it not to cool down really well and the increased heat can cause the fuel in the tank to boil if it's bad enough. If the vent in the fuel cap is plugged and the gas in the tank gets hot it tends to pressurize the gas tank. This can cause the saw to flood out or load up.
Change the gas cap or clean out the vent filter. If you can get to the cylinder clean all excess oily sawdust from the cooling fins.
If you get the saw running your probably should readjust the mixture settings.
You need to set the mixtures for the carburetor. 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.
