The needle side stroke on this machine is 5.55mm (302-4W) and 7.4mm (302-5W).
To increase the stroke, loosen screw B and move it up in the slot. To decrease the stroke,
loosen screw B and move it down in the slot. The point of the needle should be centered
left to right between fingers of the needle plate when the needle drops to the needle plate.
Adjustment is made by loosening screw C. The needle side stroke movement should
start when the point of the needle moves up from the top surface of the needle plate.
The needle side stroke movement should stop when the point of the needle reaches the top
surface of the needle plate. This timing adjustment is made by worm gear D. To adjust
