I just set up an old Janome 4612, but the handwheel isn't moving the needle.
It was, but there was a step in the instructions that had me turn a ''stop motion knob'' the left to disengage the clutch. Later instructions said to turn it back the other way to re-engage, but I don't think this worked.
The ''stop motion knob'' now does move the needle up and down, but the handwheel doesn't.
The illustration in the manual suggests that there should be a screw in the stop motion knob. I have a screw hole, but no screw. Is this the cause of my problem?
Actually you should have a "set screw" in the hand wheel. The set screw is usally locked down tight to keep the hand wheel from spinning freely. I f you can run the machine slowly and hold the hand wheel in one place but the machine continues running, then you do need to replace the "set screw". If you replace it you will find that you can offset some of the machines vibration by where you lock the wheel down. Trial and error is the only way to achive this adjustment, kind of like balancing the tires on your car.

The lack of the set screw let me unscrew the stop motion knob to far when filling a bobbin. I had to unscrew the stop motion knob all the way, and re-set the plate under it that links the stop motion knob to the hand wheel. Now all is well. And I found the set screw in the accessory box, so all is good now!
