Thanks Mad Jack.  Good to hear your engine is running better now as well  :thumbup:. 
As to your valve scoring the cylinder, that might indicate too much spring pressure...  I may have gotten lucky by brazing mine's valve plate to the spring; it means I can adjust it so that the valve is barely touching the port face, which helped a lot with friction reduction.

Kind regards, Arnold
