Why is sewing machine not moving?
A disengaged clutch, broken drive belt or internal drive gear failure can prevent the needle from moving. Engage the hand wheel clutch if you have it disengaged for bobbin winding. If the needle won’t move with the clutch engaged, unplug the sewing machine and check the drive belt.

Why is my thread bunching underneath?

By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
