Install the air line with an adapter in the spark plug hole and turn on the air supply.

Inspect the valve spring, valve spring retainer and valve spring retainer key. Install new parts as necessary.

NOTE: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve(s) to fall into the cylinder. A rubber band, tape or string wrapped around the end of the valve stem will prevent this from happening.
