I’m not convinced my choke has ever worked correctly on my ‘80 CM200. When warm, the bike we usually start on the first kick and idle nicely. When cold, it will start right up on full choke but die if the choke isn’t pushed in some. While warming up, moving the choke in or out doesn’t seem to have any effect on rpms other than stalling when fully pulled out. Slow and choppy idle until the bike warms up. Once warm, idles and runs good. Carb just cleaned again, mix screw turned out just over 1.5 turns. Any thoughts?
