Tuning Wildcat mk1 mag indexing problem

After replacing the regulator last spring on my .25 Wildcat Mk I, I had this problem on my Prairie Dog hunt. I was told to make sure the two blocks that clamp on the air tube was far enough back to allow the cocking rod to go back far enough. I just put a Power Plenum in and move the clamps back till they were against the check rest and it works perfect now.
