That tech tip is worse than useless. Far too many mistakes to list. I have wasted a few billion electrons over the past 20-something years, explaining a valve adjustment procedure that works, first time- - - -every time- - - -and virtually nobody uses it. I gave up on that Don Quixote quest long ago. There's probably a reference to "companion cylinder valve adjustment" somewhere in the archives.
