Title: wet air horn gasket
Post by: 78anniversary on February 23, 2012, 05:35:14 PM

Just got my rebuilt carb back on, (the coloring looks great by the way Cliff).  It starts and idles good, no problems yet, i can't drive it yet due to salt on the roads in michigan.  But the air horn gasket looks wet.  Is this a problem?  what would cause this?

IMO it's an unavoidable situation caused by wicking of gas by the airhorn gasket material. I've had Q jets "unwarped" with new thicker gasket installed, etc., and tried everything I could think of, but the gasket still got wet. Since then every chance I get, I feel the exposed portion of the airhorn gasket of every Q jet installed on a car that I can. They're all wet. I don't know if there's a difference in today's gasket material from original but today's gaskets will wick gas like crazy. I took a new airhorn gasket and dipped the corner vertically in a pan of gas and the gas wicked vertically up the exposed portion of the gasket for as long as it was in contact with the gas.
