Please help I'm new to the older model outboards. I have always used a 4 stroke but I just received from my wife grandfathers estate a 1954 QD-15 10 hp Johnson. I was able to tune it up and get it running, however I am wanting to know what fuel mix ratio should be used and if I should stay with the 2 cycle or use the 30 weight? Both are shown to be acceptable on the engine cover decal. What is best? and what mix ratio?
Thank You
