OK been playing with this one for a while now and I am of the belief that perhaps I just got a "lemon". The noise is horrid (no biggie) but the plastic piece connecting motor to armature bar kept popping off the motor end? Tightening the plastic screw made it no longer pop off but now it catches and I have to "kickstart" the damn thing every time I let off the foot switch. Anybody with one of these machines please offer some insight.
