Hi, I assume that you hade an AD4.203 engine in your 65. The clearance is .30mm or .012" cold or .254mm or 010" hot. Turn the engine in direction of rotation until the valves on No 4 are rocking. This is when both valves are closed. Any movement of the engine from there will cause one of them to begin to open. No 4 valves rocking, adjust valves on No 1 No 2 valves rocking, adjust No 3 No 1 valves rocking, adjust No 4 No 3 valves rocking, adjust No 2 MF don't give a figure for the rocker hold-down nuts. They are 3/8 unf so about 32 lb/ft should be OK. DavidP, South Wales
