Carburetor leakage!
I changed my spark plugs last night (what a pain that was!) and noticed a very strong smell of gas, I checked my carb and saw little puddles of gas on my manifold. It wasn't coming from the gas line, that was on secure. I looked at the gasket and it looked like it was coming from there, can gas leak from the gasket, do I need a new one (I don't know much about carb's)?

Re: Carburetor leakage! (mpro72vette)
Don't get a new carb. Check the gaskets on the bolts for the fuel bowels, thoses go bad easey. Check the mettering block and fuel bowel gaskets too and you migt also need a new accelerator pump diaphram. It is all very easy to fix, only 4 bolts to get off the bowels and only 4 screws for the diaphram. Sray some carb cleaner/throtle body cleaner on it and wipe it good. Then if you start the car agin you could see where it is coming from. PS... don't blow your self up :chevy

Re: Carburetor leakage! (yellow 72)
It's most likely the fuel bowl gaskets on a Holley but could be accelerator pump diaphragm or .......time for a kit :cheers:

Holley rebuild kits are cheap and easy to install. $20 or $30, you will also want a gallon of carb cleaner so you can soak it. We can walk you through this one pretty easy. In fact, you can probably figure this out easily yourself.
