So here it is. The lever affects the cam engagement that drops the foot. The documentation says position '2' was for embroidery and darning. As such it should drop the foot. As things are currently the ironic effect is that in position '2' thr foot rather stays up permanently. This might very well behave like everything else on this machine: Exercising all of its movements and liberal oiling might eventually free it up.
Is it stupid wanting to produce thinvs on this fucker? I might take it apart entirely. I'm confident I understand it's motions enough to get the timing right again.
