RepairClinic Item # 1810038 Aftermarket (Non-OEM) part
The gas cap on YOUR chainsaw is designed to let a very small amount of air into the tank. This is necessary because as fuel is consumed a vacuum is created in the fuel tank. The gas cap has a tiny vent to let air into the tank and equalize the pressure. If the gas cap vent gets clogged air can't enter the tank and eventually the vacuum pressure in the tank exceeds the vacuum pressure of the engine, and the engine stalls. The vent often cannot be cleaned because it is made of a semi porous ceramic material. If the gas cap vent is clogged, replace the cap.
