It sounds like using the 3700s the motor is just within its limits and using the 4200s just goes over the limits.
A 19 tooth pinion is too big for 12 turn motor, the 16 tooth pinion should help but the motor should not be getting too hot to melt solder. As the motor has recently been rebuilt if the timing on the endbell was not set correctly and is too far advanced the motor will overheat very quickly. Lowering the timing on the endbell will reduce the current draw so making the motor run cooler.

The timing is set at the lowest point....what if i remove 1 cell and make them 5cell? Will it be improved?
