I know exactly how to do it, I simply choose not to because I don't like doing it that way. I don't like gettin burned and I don't like hanging onto a moving wrench or ratchet. People have done this different ways since the beginning of the internal combustion engine with both having successful results. I think if one way was so much "wronger" than the others, we'd know it by now. I've done it both ways and I like cold non running adjustment better.
