Hey Pork chop and jvojr. Thanks for you help and concerns. Pork chop, it fires right up when cold, and I mean cold. It was a -15 below zero the other morning and it fired right up on the first crank, so the fuel pressure regulator is not the problem. In fact, the only time it gave me a problem was on a "warm" start, like it was getting too much fuel....I'd turn it over and it would go."rrrr...sputt, sputt, and not catch...on the 2nd crank it would start and then run fine. In the last week or soo It's started right up without that problem. Thanks for all the advice...maybe I had a tank of "bad" gas.
