I have access to a Consew 226. The club I belong to has one. The trouble I am having is changing the stitch length. When depressing the table button closest to the needle, turning the wheel toward me and the button drops and is engaged. Then the wheel fails to turn properly to setup a different stitch length. The machine clutch goes out (won't run the needle and walking foot). I need to re-engage the clutch every time using the button closest to the wheel.
This machine is the 226, not the 226 R-1. The stitch length indicator is located under a movable plate on the top of the arm. There is a witness hole on the side of the arm through which you can observe the numbers for stitches per inch. When the "Q" button (according to the manual) is depressed and catches, the wheel won't continue to rotate and change the "numbers". It only throws the machine's clutch and needs to be re-set.
Any help, please.
