Gene,
I am using a gravity flow nurse tank so I think my fuel supply is adequate. I have no reason to think I am losing spark. For the few seconds that it runs, it is at a fast idle and is not affected by the throttle position.

Chipper,
I knew it was a ridiculous notion that $1 bill would solve my problem, so I used a $20. It didn't help. Could I borrow a $100?

Mike
