i personally think...the fuel pump chng is a good start...there was a thread about the pro's & con's of electric pumps on here & it seemed like evry1 liked the mech pumps...no electrical probs...i would start there & then go on to the carb & make sure the floats are set rite & the power valves are ok...1 thing at a time...KISS...just my .02 cents
