Emery, Ken,
In my case, the source of the fuel smell is the carburetor
fuel bowl. The smell comes from the cold air feed. Covering
it greatly reduces the problem but is a hassle to
cover/uncover it as it is in a pressurized area (at road
speed) behind the air spoiler.
Until the fuel in the bowl completely vaporizes, the odor
persists. It is especially objectionable when I park the
GMCMh in the garage when the engine is at operating
temperature. The motorhome garage is part of the garage
attached to my home. Unless I vent the garage [with a large
(36") ceiling-mounted vacuum fan], the smell will even
infiltrate the home.
This "smell" issue has only increased as the volatility of
the fuel increases. A local restorer of carbureted collector
vehicles says this is a major complaint of owners of those
vehicles. They often argue that their late model vehicles
don't "stink" (but fail to acknowledge that those vehicles
are either direct or multi-port fuel injected [both
pressurized/sealed]).

Also, the seal around the fill spout might be leaking. If
so, when you
fill some gasoline can leak down into the inner wall to the
left of
the driver's seat and when it evaporates it can fill the
cockpit with
fumes.
