Troubleshooting -- motor cuts off when I lower foot

Post by BlindHog »

OK, I am stumped, but it doesnt take much for that.

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) :smt005

Does it sputter or just shut off? Sputter is probably fuel, shuts off is probably a short "check the kill switch and wiring" :-D

I could be wrong, but there might be a low oil shut off. Might want to check the oil level. I could be thinking about the motor I had before that one.
Wevans makes a good point too.
Good luck.

It could have a low oil switch causing it. Also most of those motors have a mercury switch. Your mercury switch could have been moved to the wrong position causing it to stall in the down position.

I think that most of those Briggs motors have a low oil sender that shuts the motor off. I had one that was just under the oil level and thought that it was fine but that little bit made a difference. Check your oil level.

As usual my technical difficulties were of my own making. The low oil sensor that Rocket, JT and others diagnosed was it.

I had never known what the correct "angle" of motor was for checking the oil. A little oil and she runs like a top again. Imagine that?
