    Stupid me, no oil

    Read the label of 2 stroke oils. They will state for water cooled engines. NOT for air cooled 2 strokes. Been there. The 2 stroke air cooled engine oil will not burn up as cleanly. I used up the 1 gallon of air cooled oil by going WOT for 1 to 2 miles on the way to my dock. It burned off the...
