I'll try to keep this short. Posted on 2 other boards, with no replies.

Does anyone know if the throttle shaft can be installed on the min-max gov linkage incorrectly? I know the top cover of the Db2 pump itself can be installed on the wrong side of the gov linkage (causing a run away) but this is not my problem.

Truck runs great at WOT, mid throttle, good timing, good power, no air in the system verified by a clear IP return line. Truck runs perfect.......

It just WONT idle after reasealing the IP. I had to bottom out the low idle screw to get it to 500 rpm ish. Idles kind of rough, but is smooth if I hold it open a little further.

So i'm thinking 1 of 2 issues. I either goofed installing the throttle shaft on the governor shaft (shaft has 2 steps) or tank sock is plugged. I know the Db2 pulls fuel well at higher RPM but not much at idle. I'm pushing through a 10 micron and 2 micron with a 12v lift pump.
