Solenoid to advance the timing at low rpms. Most people just wire it up to the fuel solenoid so it has power all the time.
if i take off waier on the solenoid then nothing changes (even on driving). but in testing the wire gives electrisity what depends on rpms and the solenoid workes to.
i think there should by noticeable some change...or not?
sorry...my english is not sou good...
No real change while driving, but should make starting easier.
it wil make starting easier when its disconnected?
