Evening All,
I have been going through valve adjustment posts and tech tips recently and I still have a few questions if someone could please help me out. Oly has a post on the TechTips about how to adjust about half of them and then you rotate the engine once and adjust the other half. What puzzles me is one f the last lines that say after you do all this you still have to do the "final adjustment." What does that mean?

My engine is running but I want to check the valves because I suspect that it would run much better.

There have been a few posts about this method, while acceptable, is not the best method of adjusting a valve and then rotating the engine a little and adjusting the next valve. What does that mean and how do you do that?

I have to say I am not a bid fan of adjusting them while the engine is running. I Know it can be done, but I would rather have the "correct" method and not the "close enough" method.

Any Help? Thanks.
