My 201 is knocking.
1956 201.
When I press the foot pedal to sew, my 201 goes 'knock'. Its in the handwheel area but appears to involve the whole horizontal shaft.
It happens only once at the start, then sew beautifully, nothing else wrong. It's all well oiled. I've taken the wheel off and the finger gear and wheel are well greased. When I loosen the wheel the needle disengages and the bobbin winder works just fine.
I've had the motor cover off and that all looks fine. The needle length lever works fine. Baffled. Any ideas? I'm new to working on them but know my way around with screwdriver.
