Car wont restart after sitting for 5min ???

So with an aluminum carb and common E10 gas blends, 10-20 minutes is about the heat soak window for the gas to be boiling in the float bowls. This will make for harder starting. I ran a 1406 on a Wagoneer for years which was an underhood heat monster. I learned a few things that reduced complaints from SWMBO that "her" Jeep was hard to start.

Crank at half throttle when warm. Closed throttle won't move enough air to cool the carb down enough to stop the boil, wide open will lean out.

If you have a mechanical fuel pump, it's normal to have to crank a little to get cool gas to the carb. Aluminum fuel pumps heat-soak worse than zinc, same as carbs. An electric pump goes a LONG way towards cutting the crank time.

An AMC style fuel filter with the return line pointing up might not look pretty, but they are also a big help.

And finally, if you can pop the hood open even a few inches when you park it will help a lot.

Modern fuel injected cars have made us forget some of the "joys" of carburetors.
