I tried it, it worked.
Cough, Cough! Bet that smelled a little also.
Thanks for the many ideas. I have a NOS pump on there from a few months after I got the cruiser. That didn't work. I am going to try Terry's suggestion first, since the higher octane does not really work in my situation. I have tried that several times before and it makes a little difference, not not enough. I really don't see why I need a return line at all. I definitely know that fuel delivery to the carb is at best - weak, but only when hot. I never have the problem in cooler months.
