Those compression numbers are a little low. You would like to see around 140 on 2 cylinder engines, so part of the problem may be engine wear. Yea I'd also look at the carbs. May be just a simple cleaning, or if they have never been rebuilt, then it would be time on that year ski. If the carb cleaning/rebuild does not do the trick, you may be looking at a top end rebuild.
thanks again for your help. Took the carbs off today and the needle valve is bad. Will purchase rebuild kit and rebuild them. I know it is a Mukuni carb. Probably is a 44. But there was not a part number on them. Just want to make sure I purchase the right one.
