Hey Guys, it's been a while since my last post. I have a +/-6year old TroyBilt Storm 28" blower. When I first start it up and engage the drive it won't move. If I hold the drive lever / clutch down for 30-90 seconds or cycle it a few dozen times it then eventually works just fine for as long as I run it. The colder it is, the longer it takes to move. I would think of it was abad belt or friction wheel it would slip all of the time. Am I wrong? Any ideas?
