Don't normally post here.. But on a Johnson owners behalf, would anyone know the pre-mix ratio for the above.<br />I hear there were a few different ratios during this era.
Yup. Don't fool around with a leaner mix. Too much oil will just foul plugs, but if you run the motor hard you might err on the side of a little extra oil (always TCW-3 only).
Unicorn, all current OMC pre-mix engines are considered 50:1 designs even though for a short period they tried 100:1 and needless to say, it didn't work with the standard oils.
