Have an 88 Johnson 110 with same choke. Just got the boat late last year and it hadn't been run much by the previous owner for a couple of years. Had trouble at first getting started. Thought I may have gotten a lemon, but soon discovered I was choking way too much. Had the engine checked out, and actually is very strong. Just inexpierence with the engine and too much key pushing. It would flood and then batteries would run down and no go. So far this year, no problem. good strong batteries are a big help.
