Turn off circuit breaker. Drain tank. Unscrew air pipe from head. Unbolt the 3/8\" head bolts. Pry off the head & intake plate & gaskets. Gently & thoroughly clean the top of the block to bare metal. Vacuum the cylinder & piston. Be aware that under the stuck on gaskets is a minute sealing ring cast into those surfaces. Don\'t cut th em off. Pry & slice with the razor blade from a utility knife all the old gaskets off. Clean any stubborn spots with Naphtha. I replaced the valve plates & restrictors per the enclosed instructions.

Installed the head & intake plate with the new gaskets. Tightened the head bolts working opposites to evenly snug with a 1/2\" drive ratchet. Did the final tightening in opposites to a moderate tightness. (no torque wrench) Reattached the air tube to the head. Check for leaks with soapy water: None!
