The RPM limiter and now the retard pills....what is really in there. Is it just a resistor, or a capacitor? Seems you could cobble up a potentiometer if it were a resistor and have a dial-in RPM knob or retard feature. Anyone got one they can throw on a multimeter..or my cool component ID/tester? sure looks similiar......1 turn = 100 RPM? Just wire 1 side and middle to use as a variable resistor.
