Your fuel smell could be heat soak.

After the engine shuts off, the carb rapidly heats up, without air flow to cool it. Then the gas boils in the bowls, the pressure forces the fuel out into the manifold where it evaporates and exits through the carb.

A quick check would be to shut the car down outside and let it get dead cold. Then push it in the garage and see if you get the gas smell. If no smell, then heat soak is possible.
