Your problem is not needle, needle 16 is ok but you need to check your shuttle and bobbin and even change your needle if it's cutting too much,of after trying all of this, you can get a qualified technician to help
Please (up , the place you separated the yoke and the cut ,that 1inch date ) the place you move 1 inch at the cup but not at the yoke , the yoke will be big because you did not move the measurement like you did for the cup , is what he gave me hooo the yoke was biger
