Valves

#1
Hi:
Just took the head off of my GX200 clone. The valve seats look pretty good, but the valves themselves are black, top and bottom. It appears the motor was run with an extremely rich carb. This a refurbish project. Also, one valve comes out easily but the other valve is captured by the slot it rides in(not sure of proper term). Learning as I go. Thanks for any help. Hope I provided enough info. Sorry, my question was should the carbon build up be that great. Without a picture, they look like the inside of a tailpipe on a car.

What valve is it? I believe only the exhaust valve has a lash cap.

This means that the rocker puts direct pressure right on the stem of the intake valve. It causes mushrooming on the end of the valve, which causes it not to fit through the hole it resides in.

A small file will do wonders :thumbsup:
