Iam tring to find out the correct feul/oil and spark plug setting for this motor.I do not have a owners manual.I currently use a 50:1 F/O mix and spark setting of .25 is this correct? Any help would be greatly appreciated

"Bill, the 50:1 is perfect (regular unleaded gas and TCW-3 rated Marine oil) and if you are using NGK plugs (B8HS is what the book calls for), the gap should be .024."

"Graham,

Thanks again,
Bill"
