what is the minimum fuel oil ratio that i can run in a 1955 evinrude 7.5 fleetwin. the cover has a sticker that is in quarts and gallons, i figured the ratio to be 20:1. this seems like alot of oil.<br />can i run a leaner mixture without causing engine damage? this motor runs rough at idle, could this be caused by too much oil in the gas. i changed all of the ignition components and it runs a little better. but rough at idle. also gunked the carb and installed carb kit
