I think I have seen this one asked before but since it didn't apply, I didn't pay attention. My '76 2002 stalled after running in 90 degree weather for 30 minutes and then sitting shutoff for 10 minutes. It wouldn't start and I had to leave it overnight. It started the next morning no problem. I have a 32/36 water choke carb. Everything else is fairly standard. What should I look at?
