i currently have a carter comp series carb on a 460. every time i shut it off and let it sit for a few hours, it takes forever to get it to start. somehow it is bleeding the fuel off or something. cannot figure it out. its about a 600-650 cfm. will be changing in the future but need to figure this out for now.
Thanks!
thanks guys, was not aware the fuel could vaporize like that. and will go back and check, change hoses etc. since i could not find external leaks was wondering about the fuel pump. but if it is the fuel pump would, or can it siphon the bowls empty?
Have same trouble with my 460. Have a 850 Holley double pumper on mine. Have more trouble with it since I put a inline fuel filter on it. Was told to move filter from next to tank to next to the carb, but still no change. Its a wild goose chase .
moving the filter to the engine bay will make it worse, Doing so makes it easier for the fuel to heat up. Want to fix it? Install a elect fuel pump. See the prob is todays fuels have lower boiling points.
Yes, the phenolic spacer is just plastic. I used to run one on my 460 when I had a carb, and it not only insulates the carb but is supposed to make the fuel mix better. But it sounds like you have an air leak and the gas is siphoning back somewhere.
I've ran several old Chrysler products with Carter carbs and they always boiled the bowls dry. The plastic spacer helps. Gas can't siphon back to the tank. Some carbs have plugs in the bottom that can leak. Restricting the exhaust crossover in the intake manifold will cure the boiling issue.
Yo boss 429, thanx for the info. I didn't know about the lower boiling point. Will move the filter back to next to the tank. Do you have an idea as to what the temp is on the boiling point? Would installing an airgap intake help?
