Hello everyone, first post for me.
Our 1502 will not restart once it gets hot. We are leaning towards an electrical issue but can't nail it down. When hot if you kill it at a stop sign, you're going to be there for an hour waiting for it cool down then it will restart. Fires up fairly easy from cold, but will not restart hot. The timing is on, new points and condenser, valves adjusted, and the battery is good. We have read that, the fuel can empty/boil out of the carb. We can't wrap our heads around it happening, in a matter seconds, from when the car is stopped. Hoping someone here can maybe direct us to something we are missing. Thanks in advance.

That's not too uncommon. If it does it immediately after stopping the engine when hot, then trying to re-start, it may be that the starter is dragging. In such a case, the starter will often sound like the battery needs charging. Another possible cause is carbon deposits in the engine. Driving the car will often reduce them. Timing that is just a little too far advanced can cause hot starting issues, and if the distributor advance mechanism is not working as it should, the timing can be advanced too far even if the initial timing is correct. You might try driving the car to fully warm it up, then set the initial timing about 3 to 4 degrees later than it is, and see if that helps. Try it several times to be sure. Another way to check for advanced timing is to get the engine hot, then crank it with the ignition OFF and see if it cranks faster. You need a full size battery in top condition and the correct cables and connectors in top condition to assure reliable starting under all conditions. ** While it is not uncommon for older cars to flood when stopped in hot weather, it usually takes a few minutes after a hot stop for this to occur, and the same is true for a dry carburetor bowl condition. If the car is hard to start immediately after a hot shutdown, it probably isn't a fuel issue, UNLESS you have a sticking choke or a sticking manifold heat valve.

I just have the 120, but mine has the '53 327 with the 4 BBL Carter Carb. That said, she will not always start hot either, and NEVER after a stall out at a light, turns over but cannot get gas. I suspect a bad accelerator pump acerbated by the modern fast evaporating fuel with ethanol in these parts. I have found a sure work-around for mine. I made a cup holder that is designated for a Gatorade bottle I keep filled when I refill the tank. A short shot right in the carb results in an instant fire-up.
You could test this in the privacy of your garage by taking her out for a run, shutting her down in the garage, then trying to start her. If she doesn't go, try a shot of gas and see if she responds. No harm done as if it doesn't work, simply empty the bottle into the gas tank and go to the next plan.

You probably do have a fuel problem. Might be low float level and/or accelerator pump issue.

I agree, but it does not show up at all during running any other way so I use the bottle.
Here is a shot of the holder, put it on the passenger side so in easy reach to priming the carb.
