  • 90hp ignition timing

    I'm trying too adjust the timing on my two stroke 90hp from 1986. I've replaced pistons and rings and therefor needs to adjust the timing a litle. What is the preliminary link lengths related to the timing, my manual seems to be wrong at this point (bought it online).
    It also describes the timing degrees to be 9-11 degrees ATDC when ideling, and 21-23 BTDC at full advance, is this right for this model?
