Those were great motors and extremely popular. It is probably the mix
ratio
if it smokes a lot even after it is warmed up but it could be adjusted a
little rich too.

I think it might be worth the investment to get some fresh gasoline and
some
OMC/Johnson/Evinrude 2 cycle oil and mix it accurately to 50:1.

Lloyd,
I would do what Bill suggested first with the fresh gas and correct oil
mixture. If it still smoke real bad you might want to look at the
Carburetors. They may be loading up causing the rich gas/oil to dump in the
cylinders. Remember Gas burn better then Oil
