This was a frequent failure in the early days ... caused by the little spring
(that holds the check ball inside the lifter) breaking. remove the lifter and
disassemble by removing the retaining ring at the top. It is a good idea to
not use a different lifter against the cam so get a spring from another lifter
and reassemble. Place the reassembled lifter in a small can of motor oil
and pump the piston up and down with a push rod to refill the lifter then put
it back into the engine and adjust in the normal manner.
