Problems in the Fuel System This vent is just large enough to allow air into the tank, creating enough backpressure to aid in fuel delivery to the carburetor. Surging is also caused by water that got into the fuel. A mower left in a heavy rain or condensation on a hot summer day can choke the engine.Are you supposed to run a lawn mower wide open?
