Just in case anyone else out there has this same problem, I have been dealing directly with the tech reps at Happ (who have been great I must say) and together we have figured out what the problem is. With some ultimates, after you lock the shaft, actuator and washer in place with the e-ring, there can sometimes be too much compression of the internal spring causing a restriction in the amount of movement then allowed in the shaft. The simple and effective solution turned out to be simply don't use the zinc washer. If you lock everything else in place correctly but don't include the washer, it will work perfectly.
