I have a 1980 Toro 421 snowblower Mod. # 38010. Does anyone know if there is an adjustment for the Auger belt or should I just replace it and hope that helps. It is not throwing like it should. The shear pins are not broken. The pull start also seams to freeze when it gets very cold out and will not engage the engine. It pulls and rewinds but isn't turning the engine. If I bring it in the basement for an hour it starts to work again. Can it be lubricated with something to help it keep from freezing?
Any help is greatly appreciated.
Couple of things i would try
1)Put some carb cleaner and let it run through,see if that improves the cold starting.
2)Change oil and see if their is any water in the oil you took out.
3)tighten the auger and drive cable .mine used to be a bit loose and too much cold weather with some wet dirt would not engage .But once in the basement for an hour it would work .
