I have a kohler engine which I bought as a K321. It is minus the shroud so I don't have the model number. It has a 3 & 7/16 piston. It has K / 5 cast in cylinder block. Need to know if this is a k321. Bob

K301 12hp standard bore is 3.375" (.030" over would be 3.405" bore)

 

3-7/16" is 3.4375"

 

K321 14hp standard bore is 3.500" (.030" over would be 3.530" bore)
