Well its been a long week, having difficulty posting picks so here is what I have,I was able to find instruction manual on( nick-o sewing mach llc) and it showed that disk( pic 6) was to adjust the"sewing foot stroke" from A@ 1.5mm to F@ 6mm by pushing button on top of machine locking the shaft and then turning the hand wheel to the new sewing foot stroke, releasing button and its set.I made contact with a local shop and was told to rotate bottom shaft until feed dogs were flush with needle plate rotate the top shaft bringing the needles down until they were flush to dogs,then gently slider belt back on and it should be timed. I slipped a feeler gage(.005) on top of feed dogs then lowered needles to just touching and slipped belt on, second time worked great and was picking bobbin thread in short order after sliding belt tensioner in and rotating until firm then tightening set screw. Pic (6) also shows the broken off oiler hose connection to site glass and am hoping once all else is working to gently drill out broken part and epoxy a brass 90 to reattach hose. Lets go to the bobbins as the left is working nice but the right will pick when I hand turn and not pick under power,it is also missing parts under the bobbin housing looking under mach. and would love to send the pick but I am close to inept @ computer crap. Not quite ready yo take the other side apart to see if I can fab. something, but close. Thankyou Uwe and gottaknow
