Bless this thread and much thanks for Owe, Wizcrafts (who consistently come up in my Google searches when I'm troubleshooting) and to Dave4. I was having the same problems with my Chikon (aka Seiko aka Consew) STH-8BL and Dave4, yes, it was the all mighty timing that I was afraid to touch after playing with tension, check spring, feeders, etc., but which, following your directions, has improved my machine (that I just got off Craigslist for $250) from hair pulling to at least acceptable. Just joined the forum to say thanks (and I'll probably be back with more questions which, of course, I will search the hell out of this forum for first).
