Diagnose and repair a failed fuel pump. This motor was running poorly and stalling repeatedly. The first problem was that the motor would stall and the owner would have to pump fuel back into the motor by squeezing the primer bulb. Motor would run ok for a few minutes then shut off again, and the owner repeated the same process. Eventually, as you will see in the video, the lift pump failed and filled the crank case and valve train with gas and the motor was so bad off it wouldn't start or run.
