I have a 1969 Johnson 20 HP electric start model # 20RL-69D The motor ran ok, but not great when I got it about 2 months ago. Now it won't idle and coughs and dies. It is also hard to start now unless you have it at a high throttle. It runs fine at higher rpm's and has good power. Is this a spark issue or carb???? I have not done anything to it other then I put in a new impeller. Where should I start, new plugs? Carb kit? I know just enough about boat motors to get myself in trouble. lol
