My 1951 3100 seems to produce a pretty pronounced gas odor if the garage sits closed overnight or what not. It has a replacement Spectra tank in the stock location. I re-used the original cap. Can’t seem to locate any leaks.
Theories:
1) Replace the cap? Anyone got a part number?
2) Fuel leaking by the carb into the manifold after shutdown. It’s a Rochester B so anything is possible. That piece should be easy to check with a flashlight down the throat. But not sure what the fix might be.
And I don’t see how a few dribbles down the manifold would produce this magnitude of smell.
