Great video by the way, but sorry that you are having trouble. How about changing to a set of the old black roller rockers and see if it fixes your problem? If you don't have a set of rockers I can ship you a set to try.
Thank you Mr. SlantRacer!
I have a set of those old black roller rockers I am saving for the "killer" 210 engine.
Don't want to use them up on this old junk engine.
You know I watched the video, I look beat.
Maybe some energy drink or coffee would help me.
I am glad a few posts ago I said, I "may" have found the problem.
"may"
This is a better video, with loose rocker cover nuts!
