Hello all again. My question is when I came out to start the sled, and try to go too soon. I get the machine not wanting to go as it is still frozen. Today I gave it more gas as I thought I was slipping on a hill I was on. But no it was just still frozen up (-38C today). SO I got a lot of smoke and burning rubber smell. What was smoking? The drive belt, or the track? Where is the friction happening to make it smoke? What is more prone to slip? The drive belt or the drive for the track?? Thanks all!!
