Q-Jet leakage woes
 
It there such a thing as a quadrajet that does not get soaked with fuel from leakage around the air horn gasket within hours after installing. I know about the whole overtightening of the bolts thing but this was not me I swear. I actually bought it off of e-bay and it was in very good shape except for the fact that there is about an 1/8 inch deep gouge in the airhorn around every mounting bolt hole!!!!!

What is wrong with some people.

Will permatex 3H prevent this or will I just be wasting my time.

That would be the secondary fuel well plugs. I have epoxied those to but what I am talking about is the top gasket just under the airhorn. When the mounting bolts are overtightened it warps the airhorn and it doesen't seal properly even with the gasket in there.
