Thanks CenRacer1 and Rolland. My MT2 with the OS .18 works great. This is regarding my MT2 with the factory NT-16. My MT2 with my Epic .18 is doing the same thing. I worked on both of these MT2's, not the OS .18, recently, so Im sure its something that I did wrong during re-assembly. Any other suggestions? Is the turning out of the set screw that critical? whats the max number of turns out?
