Hi,
I have a 1973 J&S 540 that has a small round cover plate on the top of of the valve control panel. It's just below the table shuttle valve, Underneath this plate is an adjusting screw with a locknut. Can anyone tell me what this adjusts?
Also looking for period correct documentation for this machine if anyone has it.
thanks
Steve J.
