So, if following the mid-lift scenario, at max lift am I correct in thinking the roller should be at a position more towards the intake side of the valve tip as I originally thought?
BTW, the Comp diagram uses "1", "2" and "3" for the positions of the roller across the tip of the valve, not "A", "B" and "C". So is your "A" above = 1, "B"=2 and "C"=3?
Thanks for your time.
