I have 9 Zenith carbs. When I place just the bottom half in my vise and fill the bowl with gas to the 5/8" level they all will wick gas up the inside of the bowl, collect on the gasket surface and overflow to the outside of the bowl. The GAV and jets are installed. This has nothing to do with the float valve or any gas line connections. I also have the bottom half of a early Holley carb. which does not leak using the same testing technique.
Can anyone please explain if this is common to all Zeniths? Is there a product to apply inside the bowl to seal it?
I am baffled!
Thank you very much for your input!!!
