Thanks to George Vollema, I finally got it with the flat blade screwdriver technique. Then I had to figure out how to tighted the set screw, which is in line with the governor stanchion. I removed the spring barrels, manipulatred the motor frame and finally found the right angle with which to tighten it! I had to get a screwdriver with a long skinny handle too. Now I am off to buy some washers, and I will hear it play for the first time! Thanks for your suggestions! John
