Hi all! Having an interesting problem with my carburetor that i would appreciate some insight on. When i park the car after a long run, the carburetor floods after a few minutes. Makes re-starting rather difficult. I have nitrophyll floats and they don't seem to help. I am assuming the gas in the line is just boiling and forcing it's way past the floats. Is there some kind of a return line i could plumb, or would a pressure regulator help? I have a stock, mechanical fuel pump.
the question to me is why is the gas boiling?....does the line sit on something hot?...like against a head or something... If you have a clear fuel fliter I would watch it after you shut it down to see exactly whats going on. Just thinking out loud...
I wish i had a clear filter, but i did away with it after talking to several people who had theirs break on them (in the middle of nowhere too, ouch!). I guess i hadn't really thought about it being near something hot (my filter sits relatively close to the thermostat housing). I guess that would make sense, wouldn't it! Is it a good idea to get a regulator anyways? My fuel pump puts out 7psi when cranking (dont' know about running). The carburetor is a little something i made up, but it works well. I have a Proform center body ("750+ cfm"), double pumper, Demon metering blocks, Holley bowls with nitrophyll floats out of the demon, and holley baseplate (modified for four-corner idle). Kinda funky, but it works better than anything else i've tried.
I wouldnt worry about a regulator unless I was usin an electric pump. If your worried about the filter housing breaking just carry a backup. I was thinking of wrapping mine in insultube foam just in case. I like being able to see the gas gettin to the carb and how clean my filter is at a glance.
