Flat cars are easy to break needles when they reach thicker cloth. How to adjust it?

This is the simplest, hehe! First of all, change the needle thicker, or change the imported needle!

If it's still broken, it's in the wrong position. You can raise the needle about 2.5, and hook the shuttle tip a little above the eye of the needle. The needle just sticks to the shuttle, and there is no gap. Curved needles are untouchable.

Tune it exactly my way. Give it to me. Contact me if you don't understand.

I have been a mechanic for more than ten years, and I can help you solve any problems easily!
