12 volt conversions are no big deal, but I would stick with 6 myself.

You said the points closed up. The means the dwell would increase greatly, which will overheat the coil. Normally current only flows about half the the time or a bit less in the Model A coil. As the points close up that means the current is flowing for a longer period of time vs. the off time (points open).

My first thought was the gas is boiling in the carb and maybe the fuel line. What kind of gas are you using? And,hot hot is the outside air?
