i have owned this motor since new. always ran perfect until stored without rinsing for 5 years. started in a tank on 1st pull, ran 3 or 4 minutes when water stopped and steam started to come out telltale. motor seized and again i put it away for 5 years or so. took it apart and cleaned all cooling passages, installed new t-stat, impeller,plugs, cleaned carb and tried to start with no luck. i have checked timing, valve adjustment, spark, and compression which seems low at 80lbs on top cylinder and 90lbs on bottom cylinder. also it seems harder to pull than i remember, maybe because im 10 years older now. i would love to have this motor running again. anyone know what the compression should be or any other things i should check?
