I haven't used a 90/14 on this machine. I've always used a 100/16. The reason for that size is because my newer Heavy duty Singer sewing machine didn't like 90/14 size. Needles were constantly breaking on me if they were less than a 16. I will have to buy 90/14 size just for that machine. The thread size is a 30. Would that matter in the size of needle?
