First try timing it with System 134-35 needles. They are frequently used in Pfaff machines. The System 190 are much longer and would be used on high lift machines to allow one to sew thicker material. You could check if your model was originally a high lift, or standard lift. "Lift" in this instance means alternating foot height during operation.

 

Ahh okay I get it :D I am using the 134-35 needles. I have the standard lift, about 8mm I think. im still getting the perfect adjustments ind. Right now, needle is perfect, also stroke. but presser foot is not moving, so I have to figure that one out later this week .:D

this may help - you have that same problem on all kind of triple feed machines. Screws may be slightly different but solution often is the same:

It is set at its lowest setting for the height of the foot walk.   Feet not in sinc.   Set the wing nut up to mid setting.  Loosen the two screws on the top shaft at the back on the end above needle.  Let inside presser foot go down to throat plate.  Bring needle down to where it enters the inner presser foot and just  at the top of the throat plate.  Tight the two screws on the top back shaft.  Outside foot should lift.

not exactly sure where and when it get stuck but if the outer foot is in the shown position Id loosen the 2 screws and lower the foot bar.

So I found a problem, not dont know how to fix it

have you tightened the set screw that hold the long bushing in place? Maybe try loosening it, then shove the foot bar up, leave it up and the tighten the screw again. Know what I mean? The foot bar would line up the top and bottom bushing - maybe... wild guess but worth trying.

Take both bushings out and see if they fit on the foot bar shaft.  If so, that means when the set screw tightens up each bushing, it is moving it just enough that the needle bar is binding.  Can you polish the inside of each bushing?
