Review on Briggs & Stratton 795027 Fuel Tank Cap: Perfect fit for 134400 L-Head Engines, 7-12.5 HP Vertical Engines by Jason Staggs

I eventually found out that the problem was that the existing gas cap was defective. There was no ventilation hole on the inside of the lid. When I started the engine, a vacuum was created in the tank, preventing fuel from flowing into the carburetor. I ordered this cap. Problem solved. The engine runs like a champion. I never looked back
