Good morning. 1983 Johnson 200hp Sea-Horse. I bought some carb cleaner, ran it through per instructions. I did notice an improvement, in my yard. When out on the lake, still wont idle that long (5-8 secs) but in my driveway, I have to shut it off. I looked at my plugs, which were new a couple of weeks ago, and they looked pretty fouled, is that from the carb cleaner, and should I replace them now?<br /><br />also, please look at this picture, see if it makes sense to you.<br /><br />Thanks
