I have posted this many times on both forums. I purchased my Ariens 1128dle new.
The first season we got his with heavy wet snow that quickly turned to rain. My Ariens turned into a sausage maker. Slush would fall out of the chute like a Sweet Italian sausage and then plug.
I was discusted with my machine and ready to sell it. I put the Clarence impeller kit in and it became a new machine.
It goes through the wettest of snow, slush, and even throws water like a cannon. Without this kit I would have sold my machine.
My Honda's throw like that right out of the factory and no need for the kit.
I have also installed them on many other machines and have never had any problems.
