I'm in the middle of my first wood boat restoration (1953 Reinell 18ft). What a job! I have a Gray model 70 that runs fine but smokes something terrible. The smoke isn't water or oil but just an over rich carb. The one mixture screw I see bogs the engine when turned in and revs the engine when let out. My question being how do you lean these engines!
Also anyone have the year and HP on the model 70's
Thanks Jeff "
