## Discrepancy

DURING DIFFERENTIAL COMPRESSION TEST, AIR WAS HEARD LEAKING FROM LOWER CYLINDER AREA.  COMPRESSION WAS 40/80.  USING LIQUID LEAK DETECTOR, FOUND AIR BLOWING OUT FROM A CRACK IN CYLINDER FIN.  REMOVED CYLINDER FROM ENGINE AND NOTED A CRACK IN THE COMBUSTION CHAMBER RUNNING FROM LOWER SPARK PLUG HOLE TO INTAKE VALVE.
