Have to figure out why the ball studs on each end of your z-bar aren't level. That likely a big part of the popping.
The adjustment rod should be really close to level, as should the z bar arms.
Diaphram clutch has a bunch of arms where the throwout ride/engages. A Borg&beck usually has 3 really heavy U hoop looking arms. Look here at the brewers site
