So after looking the car over last night, I found 2 problems. First, when applying the brakes, the disc would touch the face of they flywheel, which explains part of the problem with idling. Second, I found a piece of coiled metal shaving inside the carb sprayer bar, which was likely limitingfuel flow and contributing to irregular idle.
I fixed both issues, buttoned it back up and had it out for a test this am.
Insane power, steady idle, and never got over 205degrees head temp. Blowing lots of white smoke, it could easily be leaned out further, but I can't keep it straight as it is!
One note of irony: I swapped out the glitch-o-rama am radio with a spektrum rx and my 3pkS . It turns out that the cars onboard switch is bad and causes intermittant connections over bumps. Didn't notice with the am radio, but the spektrum locks out for up to 3 seconds when power is cycled, so I wound up losing control into a parked car's tire and cracking the front body mount plate.
Time to find some white kydex sheet.
. Putting the glow ignitor on(or taking it off) made the servos go nuts every time. Makes me really appreciate the rock solid signal of the 2.4ghz stuff.
