Re: 1986 Johnson 110 hp.. has rough idle any ideas how to fix a misfire?
Is your idle miss a lean sneeze? A miss every few seconds-like a cough? If so, it's a carb problem, not ignition. You may need to tear into your carbs and clean the passages inside with a carb cleaner product. The lean sneeze is only an idle issue. Does not explain any high speed problem.
