Interesting, I'll be waiting on your feedback on how it works.
I really never considered the old Sears blowers to be problematic (i.e., preform poorly) only the heaviest (water laden) snow caused plugging but I'd expect those conditions to be TOUGH for any blower. I do however have one modification to my first Sears/Roper single stage blower and that is outboard Fafnir bearings on the rotating member (can't think of what the spiny thing is called).
