I am having a problem that I need to trouble shoot that I have posted here http://www.snowest.com/forum/showthread.php?t=108719. The problem for me will be replicating the problem. As long as you don't over rev is there any issue with removing the belt to run the engine? Has anyone ever hung the back of their snowmobile from the rafters in the garage to spin the track. I am worried I won't be able to replicate the bogging problem I was having because it didn't start until after about 45 min of riding, then it was present for the remainder of the day. We had to drive 2 hours to get to snow and I don't have that kind of time to tinker.
