On the side of the motor, there is a cover that's about one inch
wide, and three inches up and down. It's held on with two bolts,
you'll need 1/4 or 5/16 nut driver. This cover exposes the ends
of the valves (you will see two coil springs). This cover is also
a check valve. Every time the piston goes "down", this valve
releases a little bit of air. Soak the cover in gasoline or
kerosine for awhile, dry it out, and see if that helps. They get
full of grease and junk.

Any idea where the plate would be ? I have looked the engine over and
checked the parts schematic and can't find it. Rick
