Check for spark at all of the plugs and do a compression test.

Re: wont run

Your post is a little hard to read and understand.are you saying when the motor is tilted up you can put it in gear and it runs, or does it stall in this position too?

Re: wont run

Neutral rpms in gear have to be 750-800. Lower than that, it will cough out under load.

I'm thinkin if the rpm's check out then the problem is most likely fuel related. Sounds to me like you may need to check your carbs (maybe the float level). If the engine seems to engage only while it's tilted that could be your problem.

I had a similar situation where the engine wouldn't choke so I would manually tilit her up to get her started until I had time to fix the problem.

Hope that helps!
