Soon I will reinstall the outboard and today I purchased from West Marine a Seloc repair manual. When going through the book it stated that most engines in the 2 - 35 hp range use a 100:1 fuel mix is that correct ? Seems pretty lean to me. My engine is a model # J30ECUB so it is a 1987 model year. So the question on the table is: what is the correct fuel ratio for this engine ? Thanks
