Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

In theory it should work.  I don't undrstand how it realy works. Snow blower housings are NOT perfictly round. Only the low spot  (spot with the closest distance with housing )will get wiped. All impeller blades will be worn to this low spot during the brake in period.  So in reality it is never a clean swipe , Only the low spot gets wiped clean. The other areas will still have a gap. How big a gap will depend on the out of roundness of your housing. This area the impeller scrapes clean also scraps off your paint . Your housing will then rust away.   Then what.   Buy another  housing or

BLOWER !!   I believe Hondas pump so good because there housings are rounder and there impeller clearances are tighter from the design of the unit.

Many snow throwers have excessively large gaps between the impeller blades and housing.  Some as much as 3/8 to 1/2".  My old Craftsman machines were between 1/4 to 5/16 when new and likely more than that after ten years of service.  Sand and gravel will cause enough wear to increase the gap.  My new Simplicity has a much closer gap.  It looks to be around 1/8" or less.   The Clarence kit reduces or eliminates the gap  when installed and will remain that way until wear and tear removes enough rubber to create and/or enlarge the gap. 

I've never used the kit because my machine throws snow as good as anything I've seen in a hand operated snow thrower.   Anything I've read about the Clarence kit has been positive provided the machine being modified is mechanically capable of dealing with the additional load that the kit will put on the impeller.
