Tink,
OK , you win ,it's boiling , evaporating , perculating , whatever.
Gas is very volitile and evaporates quickly. My bet is the carb. is almost dry.
I didn't go out last weekend and not today either:mad: damn weather. Maybe tomorrow:rolleyes: , and my quadrajets will do the same thing:( crank , pump , crank , pump , crank ,cough , cough , sputter , crank , pump , VARRROOOOOOM:D , and the chokes are working. Once they start , they run fine , no stumble , no hesitation.
Until the day comes we all have FI , I think it's just a fact of life:rolleyes:

It makes sense that a vented fuwl bowl will eventually allow the gas to evaporate. But the wierd part is, my old holleys dont do that at all. I can go a month and bang, they start right away. I wonder if the large accelerator pumps I have on them keeps fuel in them?

Formula31--- I agree my Q-Jets did just what his are doing. I changed over to HOLLEY HP 950's and I no longer have the problem.

Your both right there;)
My last boat with a 540 and a Dominator could sit for two weeks and 1 pump in the parking lot while I turned the blower on and when I got it in the water it started like it was warm:cool

PS That also had 50 cc pumps on it. Primary and secondary
