I picked up a 450 Snowblower this past weekend in what I would consider to be decent shape. It was partially repainted from the original white but is rust free and mechanically seems sound. I was hoping to run it on my 1987 2072 in the event we ever saw another snowfall in SE PA (seems unlikely).

I have some concerns about actually using it, I spun the main pulley and noticed it took approximately 2.5 turns to complete one revolution of the blower fan, this leads me to believe the gearbox was replaced at some point with one from a 451. I also observed the main pulley is about 5” in diameter and not 6" as the 450 should have.

Any thoughts on whether this will actually work? My thinking is that to compensate for the 451 gearbox swap a smaller pulley was installed to speed the blower back up to its original operating speed?
