Recently acquired an IH U-6 power unit S/N UBK10448 which I believe is a 1951 model. It is hand crank but I don't do that anymore so I am looking for a sharter for it. The IH part # is 60205D and the Delco # is 1107926. Any leads appreciated.
Also, This unit is gasoline only and has never been overhauled. Would it likely have 3 7/8 flattop pistons?
