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.
