I think I will have to do the 1/4 turn trick as they are worn and I can imagine a feeler gauge doing a good job. Maybe Aussie Bill can explain that sequence I saw a while back.. Do I do the adjustment cold ? and what am I feeling for , as the pushrod starts to bind while screwing down then back off 1/4 turn while at TDC? I only want to do it once and get it right..
