'65 Mustang gas odor after driving?

[65 Fastback]

Hi. To anybody who is familiar with a '65 or '66, is it normal to smell a gas odor in the garage after a drive where the car heats up? As soon as it cools off to some degree, the odor goes away. It's only after a drive. Nothing inside at all or in the trunk. I assume that the gas in the carb is evaporating when the engine is hot. The plugs are running normal in color. Thanks.

If nothing is leaking or seeping anywhere, I'd say the smell is normal. We're used to newer cars with cats and charcoal canisters and the like that pretty much eliminate the smell. But with the vintage Mustangs, you end up wearing a little of that 93 octane cologne. I love it when my garage smells like that - it means I've actually put a few miles on the Mustang!

Now that's my kind of thinking...thanks

This can be caused by the needle/seat assembly in the carburetor having a small piece of debris in it. This will cause the fuel to drip from the carb into the intake manifold. This often caused these older cars to flood if the car reached operating temperature, was shut off, and attempted to be restarted after 10 minutes.

It's fuel percolation or heat soak when the heat from the changes the liquid fuel to a vapor and escapes through the bowl/fuel reservoir vent. After you shut the engine off wait about 20 min and watch the vapor coming out the vent common on the 4100 carb.
