Aw, someone is running ethanol contaminated gas. Methinks you’re experiencing what was commonly called vaporlock back in the day. Make sure all gas lines are as far from th engine and radiator as possible and consider insulation around the fuel filter. You might try an insulator between the carb and intake as well.
