I have a 1963 mercury 650, 4 cylinder, 2 stroke. I live at high elevation and the motor seems to be running really rich. It pooches out when you give it throttle. From what I've gathered the idle mix is adjustable, but the high speed jet is not. Is there replacement jets ? Is there another way to lean this pig out? And when I do get it leaned out will my oil/fuel mix need to be changed?
