Hi,
(Geez, another boating-related topic! I gotta stop...)

My 1989 Johnson 15hp smokes a lot. It uses so little fuel that I've
forgotten when I fueled up, but I always put in 50:1. Is there other
reasons apart from too much oil in the gas which would make a 2-stroke
smoke? Is there a way to find out what the ratio IS (I might have
mis-calculated)? I want to sell the engine, and it's a Hard Sell when you
can't see the engine for smoke (Koff! Koff!)

It runs fine apart from the smoke.

It the fuel is older, that could be a problem, but the oil may have
settled in the tank - needs to be mixed again - or the rings may need
to reseat themselves (run it for a while) - or the rings may be bad -
or the fuel mixture as you mentioned, but I believe that 50:1 is about
right for that vintage.

Later,

Tom
