Worked on the engine. The exhaust valve lash was a little loose but the intake was OK. Both valve guides are extruded out. I tried to drive the exhaust guide back in but it would not budge so left both alone. Set the exhaust to 7 mil. Wanted to set it to 6 mil but did not have a feeler gauge with that size. Installed a new spark plug and reassembled. It still has trouble starting hanging up on the compression stroke. After a few tries I can get it started. So I may need to do this again. But for now, I got the work done I wanted to do last week. Thanks for the input.
