So today I prepped the bed for prime and paint. Primer has to sit for 24 hours. I'm thinking silver. Body is a Navy blue
The way I understand it, mashing the gas opens the butterflys causing a momentary very lean condition. The accelerator pump(s) are there to provide fuel until the jets can catch up. Hesitation or Stumble = increase squirter size, Go then fall in rpm (struggling) = decrease squirter size. A stock 30cc accelerator pump should handle your motor IF the lever spring is adjusted correctly. I'm going through this issue right now... hope this qualifies for this thread!@any4xx, Obviously you’re a carb guy. Q: I’m running 750 Holley, mechanical fuel pump. 350. I have to down shift, (built 400), if I mash the gas.
If I don’t down shift, she bogs and hesitates...like fuel starvation.
I’ve been told to run an electric pump to assist the mech pump. Any suggestions? Thxs.
