not much to time on those. There is process called a link and synch but more than likely yours is fine. If you problem is only at an idle. I think it is lean sneeze rather than a mis fire. On that motor there is a knob on the left side as you are facing it. It will be marked lean and rich. Turn it a bit to rich. If it won't turn far enough you will need to unhook the linkage at the needle then adjust it at the carb then hook the linkage up. I am talking about the linkage that runs from the knob to the needle valve.
