I have a Honda GC 160 engine off a pressure washer that the pump went south. The replacement pump is as much as a new unit. Can the engine be used for anything else since it has a 7/8 inch diameter by 1&1/8 length short shaft. I have been told that there is nothing that will fit that shaft like clutches for a go cart, generator heads or even a pully? It bolts up great to my troy-built tiller but the shaft again is a no-go. Is it a throw away engine without the pump?
