Having problems with it only running on 2 cylinders. The magneto side cylinder is the one not working, so far I have put in new plugs. I also cleaned the carbs and installed new pilot, main jets. The spark plug looks really lean on that cylinder, I am going to do a compresion test this week. Is it possible that one cylinder is stuck. This is my backup or (wifes sled) so I don't know how much money or time I want to put into it. The sled does have about 5200 miles on it and hasn't been run much the last 3 seasons. I need some of you master mechanics to help diagnos the problem. I'm smart enough to fix the problem, just not diagnos it. The problem started last season but didn't really care cause nobody rode it.
