Carb. Problem

[Chevyman680063]

I have an Edelbrock 600 cfm electric choke carb. that i bought brand new a few years ago and for the last 6-8 months it has been giving me problems. Every few months it will start leaking gas out of the left side at the bottom underneath the throttle linkage. I have already replaced the base gasket about 3 or 4 times. Also, everytime it leaks it fouls out the sparkplugs, so I have had to replace the sparkplugs about 3 or 4 times. The carb. is not tightened down too much and it is not too loose either. It doesn't appear that the carb. or intake is warped either. I am seriously tired of having to replace the spark plugs because it adds up over time. The motor is a Chevy 350 smallblock and the intake is an Edelbrock as well. Does anyone have a clue as to why the carb. keeps leaking gas from the base? Thanks in advance.

I would pull the top off and see if the carb has junk in the bowls. Sounds like the floats are not stopping the flow of gas and it is just overflowing. Could be a vent problem or a evap canister bad. You didn't say what year truck as some vent through cap and some vent through evap canister.

Check your fuel pressure. Eddy's like about 5 PSI. Also, check your floats.

It's not the original motor. I believe it originally had an inline-6 in it. I thought about the floats maybe being the problem but haven't had a chance to actually check them out. If it is the floats then what should I do, just replace them?
