Previous set was 1045 - 5215. I thought that the sheave clip wasn't in the idler shaft groove. (Tachometer used to check setting) Clip was in the groove.
Ended today with 1015 -5193. Difference in upper speed was a change in the stop (setscrew - jam nut). I have no trouble moving / setting the indicator dial. When reassembled , the speed control knob moves easily from Fast to B+. B is 1016, C is 1068, D is 1190. At B+ the handle became hard to move and I didn't want to apply any more force.
I was careful to position Speed Control Assembly on headstock and tighten the three self tapping screws evenly. The spring steel clip strip of the quadrant is centered on the control sheave bearing. Speed Control Handle is close to Speed Control Dial , not canted on headstock.
I was able to get a 620 - 5000 range setting a greenie a week ago and thought that was GREAT, but can't get this goldie slowed down.
If it was EASY, I'd do it myself.
