## Discrepancy

TOTAL TIME 1067.8 SMOH.  TIME SINCE TOP OVERHAUL 125.0.  DURING MAINTENANCE TO REPAIR BURNED VALVES UPON CYLINDER REMOVAL, FOUND CYLINDERS GLUED ON AT BASE.  (IT TOOK OVER AN HOUR USING AIR PRESSURE AND PULLING AND PRYING TO REMOVE ONE CYLINDER).  IT SEEMS THAT A FOREIGN SUBSTANCE WAS APPLIED AROUND O-RING AT THE CYLINDER BASE.  SUBMITTER BELIEVES THIS IS A CASE OF IMPROPER MATERIALS BEING USED.
