    Default 1990 evinrude 120

    How can you tell if a motor has the quick start feature that advances the timing to help start a cold engine ???
    How does it work / activate advance ??

    Yes your 90-120 has quickstart.
    Each time the motor is cranked the power pack electronically advances timing till the motor reaches temp or aspecifided time.
    Thats a short version.

    Short the wht/blk to engine ground, this will disable QS. This makes pack stop sending voltage to timerbase which is what is advancing timing in QS
