I had been tuning my carb and ignition right after I installed the set and after I was done tuning (apx 20 minutes) the carb was "cool" to the touch while the engine was to temp with a 195 thermostat. It was weird when the bowls were cold and the engine had been idling for that long.
After I shut it down, I kept watching the fuel levels in the bowls to see how high they would go while the engine was heating up. Both bowls only raised about 1/16". After about 15 minutes of heat soak when I knew the carb was getting warmer (1/16" of fuel rise), I touched both of the bowls and the shield and they were finally warm but definately not hot. I restarted the car about an hour later with no issues.
