Bill,
Vapor lock is caused by the fuel boiling in the carburetor and making the
mixture too lean to start the car or keep it running. Sort of the opposite
of flooding the engine. My MG has never had a vapor lock in any kind of
weather, but I have experienced it in older American cars in hot weather
after a drive, stop and trying to restart. Usually is cured by waiting 1/2
hour or so for the boiling to stop and the fuel to liquefy again. That is
one of the reasons for the heat shield between the exhaust and intake
manifolds. Of course if you have a very high strung old girl, she might
swoon with the "vapors".

Would some erudite individual please explain precisely what is meant by the
term
"vapor-lock"? I always thought it had something to do with a mechanical
fuel pump's
inability to pump "air"...
