I think I have a 1992 or 1993 merc 9.9. The sn is 0D140423. I found many other manuals but not one for this yet. It seems to start fine but when you get it over 1/2 or 3/4 throttle it just does not rev out. Even with no load on it. It has only 75 lbs compression on each cylinder. I would like to find a manual so I can tear the carb apart and would love any assistance on this. I do thank you very much in advance.
