Hey KenRig... I just had the same problem with my 200... New pedal but not all the dampers were lifting... Here's what I did to fix it:
1) Per the Wurlitzer manual, I did tighten the nut as it was sitting too low
2) There must've been rust on the connection rod screw so the pedal wasn't screwing all the way in properly... It would screw in a little and then just stop... I assumed the pedal had hit the nut but in reality, it hadn't which would explain why not all the dampers were lifting...The pedal simply didn't have enough screw to pull down... So I managed to lube the screw and slowly thread the pedal again all the way up to the nut, and then it finally worked... All the dampers raised...
Hope this helps... Regulating the damper screws on top of the stickers didn't work for me so I knew it was a pedal issue.
