I have a C-145 that runs great. uses oil. but not a lot. I will be ridding along great. hit a bump and the motor spudders. I have changed the points, coil, flushed the fuel lines,tank, newfilters, everywhere. Cleaned the carb everything I can think of. Maybe the float is slamming shut? any Ideas?:thanku:

Have you tried checking all of the electrical connections. Maybe the bump is causing you to lose an electrical contact at a loose point. Just a suggestion. Good luck:fing32:

that is what i thought it was, so after not finding a problem with the wires, I ran a wire right "TIGHT" to the coil. yep still did it.
I have thoughts that get me way out there on this. like the float bouncing?:banghead3

Not sure if this will work on your model but I had a 310-8 that if you reached the back of the ignition switch and just moved it every so slightly the engine would sputter. I put a shim on the switch works fine. Also check the key itself, trying moving key just a little and see if it sputters, that could point you to the switch as well. Also there are a lot of other connections that could be giving you a problem, check them all. I can't see it being the float.

Keep at it you'll find the problem.

float bouncing hummmm when you had the bowl off did you check the float to see if it was the right depth??
sounds to me like a lose ing, wire start it up and shake all the wires and switch and take a close look at the seat and mower deck switches and ground all lose will do the same thing
