The length of the stitch can be increased or decreased (number of stitches per inch) by changing the Feed Eccentric. Remove the Screw (1183-16) from the left-hand end of the Lower Shaft.

The Feed Eccentric should slide off.

Eccentrics are marked with a number that corresponds to the relative number of stitches per inch that they feed (4, 5, 6, 8, 10, 12, and 14). 14617 is approximately three stitches per inch, and 14621 is approximately two stitches per inch. All figures are approximate as fabric and condition of the machine can retard the Feed.
