Hi!
I just got a singer 457 stylist second hand, and knew off the bat it needed to be timed. I timed it, only to find out the top gear needed to be replaced. So I looked further, and saw the belts (both of them) were dry and cracking. I ordered the parts and replaced the gear and both belts, but now I can't get the clutch to lock. I'm thinking I may have been overzealous while lubricating the machine, or I put the clutch wheel pieces back incorrectly.
The machine will go, it's a little hard to start. If I give the inner wheel a slight turn the machine will go and stop again. If I move the inner wheel by hand it moves with the machine easily, but spinning the outer wheel usually doesn't move the machine.
