I picked up a used Stihl (70/80's) Farm Boss 041 Chainsaw. Looks very clean for older one but.fires up and only can keep running about 30 sec. It evebtually loads up with gas and dies! If I keep air cleaner off so carb is completely exposed.seems to run slightly better and longer. Description Item # A045361163 Model # 041 1 X New Carburetor. 1 X New Spark Plug. 1 X New Air Filter Cleaner. 2 X New Mounting Gaskets. Added on November 25, 2019.
