Joe,
I sounds like you adjusted the escapement. The long spring on the BC retainer.

Yeah - there is the one under the thing that holds it in place - some times those come out - kind of a PITB to mess with - I had one came with a screw missing holds that thing in - got one off my donor machine to fix it. That retaining device needs to have a bit of a spring to it or it sure doesn't work. Some times they just get out of place - someone pulls it all the way out and then can't get it back together or whatever the genius did to it.

Yep that was it. It had either been bent or more likely moved so there was a big gap between the spring and bobbin case. I closed it up and now it works.

The one I had was missing the screw on the bottom of the machine - holds it in chore to do, too.
Thanks for the lesson Joe. I may need this info in the future. ~G~
Nancy, there is a spring finger on the part that holds the bobbin case in. It's the black part on the right of the case held on by the two screws. It had been moved to the right creating a big gap between the springy finger and bobbin case. I moved it back to match the one on my 401A and now it sews properly.

Grant,
I've got a couple other Singers I'm gonna check to see if this might be parts of their problems too.
.......................
I checked my Dressmaker 7000 yesterday. The gears are in good shape and undamaged. I ran it for quite a while but could not figure out why it surges when a cam is in. I compared my machine to the pics you sent me and they are the same. I even took the spring off the cam follower and used my finger to push the follower to the cam. It still surged.
So I put a stronger motor on it. No difference.
I am officially stumped on this one. Looks like it just might have to go to the LSMG.

Joe huge thanks for sharing, I am scared to death to get that far in repairs-so afraid I won't be able to but parts back together. BTW-this machine is on my WANT list, i have already collected the manual & cams...did I see a 10.95 tag on the top of that pic?

Anyone on here have a Pfaff 30 treadle or a Pfaff 30 motorized machine? What can you tell us about it?
