My model list tells me this is the Star Series SU model, white with a blue top. These were made between 1964 and 1978, so getting on for 50 years old. I am assuming that the fly wheel wont turn at all for you, when machines are left for long periods any lubrication internally dries up. You can try to rectify yourself if you are patient, need Tri-flow Oil (preferably with a long neck applicator so you can get into the little spaces), a special lubricant which also contains a solvent, and a hair dryer to add heat. You will need to take off the top cover (two screws) to gain access to the main shaft and needle swing bearing. Also the free arm top plate should be removable with a single screw. Then get into the machine and clean with a small brush any visible lint or gunky build up on shafts, lubricate, then apply heat to the metal parts and wiggle to free up. Expect to spend some time on it, before you'll get things to free up. The needle swing bearing, the arm which holds the needle often seizes up too so straight stitch will work but no zig zag. You might want to join the Yahoo group Elna Heirlooms, lots of Elna lovers there who share their knowledge.

this wheel does seize over a period of time.Remove the top cover so that you can see the wheel. It can be unseized by spraying a mixture of 20% ammonia to 80% water under the wheel. Let it sit for 20-30 minutes, spray it again and then turn it with a pair of pliers. Do NOT break it!! use a soft cloth around it if you want to protect the wheel from scratches.

SOURCE: Elna walking foot
If your SU is an Air Electronic model i.e. 80's model, Elna didn't make a walking foot to fit. However, if you've got a walking foot that is the same height from sole plate to the screw fitting as a standard Elna foot then you could give it a try. The walking foot connects to the presser bar with a screw but the needle bar also needs to hook into a secondary lever on the side of the walking foot to make the foot actually move. Probably sounds very confusing . Check the movement of the foot manually by hand turning the fly wheel to see how it works before you actually use with the motor to minimise any problems if the foot doesn't fit.
Also you'll probably only be able to do straight stitch with this foot due to the clearance around the needle plate.

There are two types of discs - single and double.
For the thinner single discs do as follows:
1.Turn stitch width knob to "0"
2. Turn stitch length knob to "0"
3. Insert the single disc
4. Turn the top selector to "A"
5. Make sure the needle selector is in the centered position.
6. You may now choose any stitch length or width you wish. I usually try "3" for the width and 1/2 for the length to start.
For the thicker double discs do as follows:
1.Turn stitch width knob to "0"
2. Turn stitch length knob to "0"
3. Insert the double disc
4. Turn the top selector to "A"
5. Make sure the needle selector is in the centered position.
6. You may now choose any stitch width.
7. The stitch length must be put on "A" - this is the difference between the single and double discs!
I hope this helps!

Have you turned the stitch width and stitch length selectors back to zero each before trying to change the stitch selector wheel? Really important to always do this.
Have you resolved this issue now?
