You put a 1000 Kaw on yours? how much work was it. I wanted to do it and need to. I was either doing a Generac or a BB Briggs. How much more stout does it make the drive pull? you are aware it places more strain on the drive? The BB would be a tight fit ? A Generac is American made. The White 530's can be bought at Surplus pumps .com. They had the RC 18's for like 279 but sold out. They may still have the CE's. Hustler used the White wheel motors because they could be had cheap. You are not getting the new Parkers for that price.
