So you are trying to get them to hit at the same time ?
Pretty sure he's referring to yoke tuning....
I would add a half twist on the left and alternate after that if it needs more adjustments. If you remove a half twist this time, add one next time. Just make sure your yoke still has some twists in it to keep the fibers tight.
Yes, he is referring to yoke tuning. However in the last pic they were high and right. Taking a twist out of the yoke will retard the top cam and do nothing to help the high impact.
Still need to know current setting before giving sound advise
