Procedure is pull the cover, remove the rocker shaft, pull one spark plug and screw in the hose to supply compressed air into the cylinder being worked on at the time, remove the keepers for the valve spring, pull the spring, remove the seal, clean, replace the seal, spring, keepers and repeat on the next cylinder. Install the rocker shaft, adjust valves (they were so far out of adjustment that I couldn't believe it). Reason for the compressed air is to hold the valves up when the keepers and springs are removed otherwise you run the risk of having a valve drop into a cylinder then it would be pull the head of time. Runs much better and the smoking is greatly reduced. Cocktail time now.

Sam, was the valve lash too tight or was it sloppy like a loose tooth?
