Question - it came with a cam on it. Is that or any cam essential to operating this machine in any of the non cam decorative stitches? If I get that far?
A cam is not essential.
Your selector is probably frozen up at the posts - dried up oil inside. I have found that oil and heat are not enough some times. I've had to use solvent on some machines. You do have to push in or pull out to make the stitch selector knobs turn. Check your manual.
