Reply to "Vapour Lock - ?"

My car also didn't want to start after running and getting hot, and if you search the forums, you'll find there are probably a dozen possible causes (hot starter motor not able to crank, vapour lock as you've mentioned, timing problems etc.). With my car, it was too much fuel getting through and flooding the engine when I shut it off hot (the root problem is the needle and seats in the carb are too large or just worn out), so I'd have to hold the pedal down and crank until she fired up.

While trying to diagnose the problem, we took off the air filter, started the car and saw the fuel pouring through the carb.

Before going to the trouble of changing the fuel pump though, check the top of the engine, make sure the carb is doing it's job and not flooding the engine - when you shut it off hot, pop off the air cleaner and look to see if fuel is still pouring through the carb we originally thought my problem was the fuel boiling. Also, check your plugs for fouling like she's running rich, then check your timing - in particular the total advance on the distributor - when I got mine to 34 degrees along with new plugs, things improved significantly in terms of hot-starting ... it ultimately wasn't everything she needed, but it sure went a long way.

That's the extend of my experience with a hot re-start problem, others will chime in on some of the other things to check.

If you do go for a new fuel pump it will be easy enough to source for the Cleveland - most auto parts stores should carry it or be able to get it quickly. A mechanical pump should be fine unless you're planning to modify the engine for serious HP, in which case electric with a regulator is something to consider.

BTW, welcome to the forum, where in Canada are you located, there may be someone nearby that can help with the diagnosis.
