| Post subject: | Go devil issue |
I have a 9hp Briggs long tail. Wanna say its a late 90's model. Ran perfect last winter, let it sit all summer and got rust in gas tank. I replaced gas tank and fuel filter and fuel lines. Also changed oil. Motor runs great while sitting level. But when I lower the prop below level the motor runs for about 30 seconds and shuts off. If I keep motor close to level it runs great in water or air but in water it's a struggle to keep it high enough. I checked to make sure there is enough oil. I took the carb bowl off and sprayed SEAFOAM all over inside of carb and around float. Gas runs through carb when tilted back. I have no idea what the deal is. Like I said I can run motor at full throttle in water I just have to keep motor as level as possible or it will shut off. And will start on first try. |

Is your carb float sticking? Just an idea. |

Is it an electric start model? Those were equipped with a mercury tilt switch; a misadjusted one could be the source of your trouble. |

Yes it is. But I took the tilt switch off of the motor, it looked burnt out. I thought that only affected the ability to start motor. Who that shut my motor off during use |

You're right, tilt switch should only impact the start circuit. One other thought is the low oil level cutoff. I think it's normally open, so you should be able to unplug it and test the impact. |

I also think it's the low oil cut off, just unplug it and see it it helps. if that's the problem they are easy to change and don't cost much. |
