Re: johnson year

Engine is a 1965 model.I believe the original oil mix was 32:1.Someone will correct me if I'm wrong.Plugs are Champion J6C gapped at .030".

Re: johnson year

O.B. is right on the year.The fuel mixture for that year was 1:50 already,but the 1:32 is the very mix that I would run.You will never have to worry about blowing your engine because of too lean a fuel.
