Have an 8hp 1995 Evinrude that has set for a while. Cleaned the carb and new plugs. Started after 6 pulls with a small shot of carb cleaner. Runs good and warmed up and set idle smoothe as always with air screw. Stoped and re started fine several times first pull. Let it set for 10 minutes and would not start without a small shot of carb cleaner. Idles smoothe. Every time it sets a while it fails to start. Any Ideas?
