I recently purchased an 1995 Evinrude 6 hp which has been sitting unused for 3 yrs. When I start it , it runs full throttle no matter which way I turn the handle ( throttle). I have a little experience with outboards , doing water pumps and cleaning carburators and such,and am puzzled by this because the linkage seems to work fine and everthng looks like it is moving properly, nothing stuck or broken and I don't think the float being stuck would do this. Before I go and rip the carburator off does anyone have a suggestion on what to look for and am I missing something obvious..
