Can't figure out what is causing it or how to fix it. The 66 doesn't do it.
Yeah, he'd be so happy to get back to you, he'd never complain again. I always say every man on earth is lucky he didn't marry me--except for one poor guy.
Here's the short answer on ocillating/rotary/vibrating/transverse shuttles:

As for the needle dropping back down, I really don't know. With a hand crank, it's usually the way the "finger" is put in the hand wheel. Not sure why with a treadle. Someone else will know, though!!
