So I have a 1977 ford Maverick v8 my carb is stock and I rebuilt it back in July of 2012. There is this tiny hole, which appears as if it was purposely manufactured, on the front where I believe the accelerator is attached. With each pump of the peddle the hole spurts gas out onto the manifold. Do I replace this part or did I do something wrong to my carb. I need help and I need to fix this A.S.A.P. Id hate to have this car burn up because of something silly like this.
I would guess that you have a hole in your accelerator pump diaphragm. Take the 4 screws out and check. Gas should not be able to get to that hole
x3 on accelerator pump diaphragm. The replacement ones in the "help" section at the auto parts stores are junk. I changed mine 3 times in a 6 month period before i just replaced the whole carb with a 4 barrel.
No need to rebuild the whole carb to fix that. Just needs a new diaphram. And needs to avoid ethanol mixed fuels. That's most likely why they're not holding up.
Both of those will be ethanol mix gas. You're looking for the station with the sign out from that says "no ethanol in our gas" It will not be a major branded station. You may pay more for it too, most likely will. I haul Citgo branded gas (when we pull on a Citgo acct) there's no ethanol in ours. I run a 50/50 mix of conventional (no ethanol) and Chevron 93 (E10-15 mix) in my Comet and so far after 3-4 years of this, it hasn't affected the three carbs on it.
