52 carl From what i'm understanding the varnish and gum are about to wipe out the spare push rods and rocker arms,fortunately you can sttill get valves exhaust at least. My last gum episode was in about 1969 on a customer engine swap. Looks like curtains for fuel pumps too,foreign junk has taken over,saw my pile of carburetors waiting for rebuilder core values to climb.
