Diverter gate in front of Orthanc tower stuck open, needs adjusting for the third (and hopefully last) time. I don't like the flipper mech they used here. Arrrggggh! Game has only 1,126 plays since new, and a few of those were 'test games' and not completed.
Took the gate out of the pawl (5/32" Allen Key) to inspect the linkage, plastic flipper bushing and linkage to the plunger. Everything looks as new.
Gate needed more vertical "play" this time, as you would with a flipper. Gate seemed to be very tight to the nylon flipper bushing that goes through the playfield. Grey link was too tight in the pawl. Although it could move, it seemed much tighter than last time mech was adjusted. Starting to wonder if the pawl can tighten itself even more to the link , if set too close? Won't let that happen again.
Fix: I set the pawl to link not more than 'finger tight' this time, with ample play between the link and pawl (1/16" to 1/8") and between the gate and flipper bushing (1/8" or slightly less). Re-adjusted the diverter gate as per inside cover of manual (Stern SB147). Back to normal, plays fine.
