Ok all you experienced A Modelers I need some understanding of the effects of advancing the throttle and power causing overheating...

Finally got the car started after a steering box leak fix, installing a 6 V Alt, fixing the brake rod contact area for the brake light switch, soundproofing/heat shielding the car and reinstalling the 12v power supply and CB radio....

As the car was idling and after the initial increase in RPM to "start" the Alt charging I was trying different settings for both the fuel and spark advance. The fuel is simple more fuel RPM increases less fuel RPM decreases.

Spark though is a totally different thing. With the spark retarded (up) the idle lopes or sounds like a Model A with it advanced (down) 3-4 notches it hums like a sewing machine. (smooth idle) my question is the smooth idle where you want to be or why is the loping "Model A" idle the norm?

Will the car warm up faster with the throttle advanced or should it just lope until warmed up.

THANKS for teaching me new things about these awesome cars!!
