Think I fixed it. So machine had a problem missing half the stitches on max zigzag. I looked and could tell timing was off. Not knowing how to set it, I lowered the needle bar, which helped. Watching more videos, I learned about the 2 lines on the bar and what they are for. I set bar height and timing was way off. Being a mechanical guy, I figured out how to reset timing on a gear drive. Had to readjust tension and it even zigzags now.
UPDATE: Just went back and added stitches to my saddle because the problem is resolved. I was even able to add bartacs with the zigzag feature. Hopefully this helps someone in the future.
