    Default 1-1/2 to 2 turns out on mixtru

    1-1/2 to 2 turns out on mixtrue screws I find it best to set them all the same. The 1988's were never real smooth running engines they ran a unbalanced crankshaft in 86/87/88. In 1989 they brought in the balanced crank to help with idle vibrations. It's the nature of the beast. You can try setting all pulsar coil outputs to be equal sometimes that will help. Not really but you can try it.

    yes sir that is correct. start at 1 1/2 turns. see how it runs and work from there. 2 turns would be richer
