Pe and all who posted and pm'd,

Thanks for all the advice. I took off the carb and broke it down. Once I had the diaphragm free of the unit, it seemed in pretty good shape so I remounted it. I re-assembled the carb and went back to the old UR17. Then i took it outside to the garage:

1. Ign on/Choke closed - about 5 flips after the gas got to the carb, it burped nicely.
2. Ign on/Choke open - About 6 flips and it sprung to life and ran like a champ!!!!! [sm=biggrin.gif][sm=thumbup.gif]

I set the needles and ran it for a bit and then shut it down and restarted it a few times just to make myself happy. Whatever was happening seems to be fixed. I'll take it out for some flying tomorrow!! Thanks again!!!!!

Bill
