I am having a problem with my Briggs and Stratton 9 HP Go-Devil (Vanguard). Motor cranks fine, runs fine with the prop and shaft level, then when I lower it to "go," it cuts off. (This is when I am in the water or when I am not.)
It ran great all last duck season and has sat up (with Stabil) and I cranked it several times over the spring/summer and it ran fine. Of course I never lowered the motor on these "drydock" tests.
What could be wrong with it? (other than the fact that this motor used to belong to Rocket)
