The valve lash is adjusted by filing the valve stem with a "Filing block" or if the clearance is too tight the valve seat is ground. All of this takes a considerable amount of time since there are four valves per cylinder. Also, grinding the valve seat requires a "small sized" Kwikway or Sioux grinder since the cylinder head and block are "one casting" [non removable cylinder head] which is done though the bottom side of the block. I still have the Offy filing block.
