    This crank is in a every day genral use motor.
    Crank had to be rebuilt for bad bearing's.
    During reassembly 2 an 3 were reversed, (by accident)
    This is discovered after engine was started
    So what the hell, swap coil lead's an give it a try.
    Still run's ok today.

    Since it's a every day fishing motor i cannot state any performance gain's.

    The point of my question is to hear if folk's have tried this.
    Tested like dyno, rpm's inproved flow. ect.
