3. Clean the inside of aluminum head. It must be free of metal chips and granular dust. Also, clean
the piston and the cylinder.
Note on Cleaning:
Clean both the inside and outside of the cylinder, especially the inside. It must
be free of metal chips and granular dust. If necessary, use gasoline to clean. Clean the surface of
the piston. If necessary, disassemble the O-ring and clean the piston with gasoline. At the same
time, check the condition of the O-ring. If the outside diameter is less than the piston, replace the
O-ring (#56) to ensure proper performance.
