A Poulan chainsaw carburetor works similarly as a carburetor on a vehicle or other little motors. The changes by it either make the fuel combination more extravagant, by adding more fuel and oil to the air blend or slenderer, by decreasing the fuel and oil blend proportion to air.
Inactive Speed Issues
Changes should be made to a carburetor when it kicks the bucket after beginning, is difficult to begin, or passes on under a heap. In these cases, the fuel and oil proportion to air should be improved. If the chainsaw seems as though it is running excessively rich, it will fire up at high rates and make a piercing sound.
