    I think that may be an air cooled powerhead.  It has a wobbler pump in the foot to help cool the midsection/lower but the poowerhead is air cooled.

    That might have been in the era where mfgs were indicating that crazy ratios like 100/1 were OK….but if it were mine I’d run it on 16:1 or maybe 24:1….and use the air-cooled version of 2-stroke oil.
