Bobbin winder Singer 185k
DH just replaced the belt. Original belt was a flat one but store was out of them so he brought home a round belt and machine seems to work ok after installation. Man at store said bring it back if it doesn’t work out. Problem is: Bobbin winder has become sluggish and touchy so I have to baby it along. I suppose I should replace the bobbin tire or could there be another reason ?
