So sorry for the complications. We just sent a machine back to the owner ( eBay) and were promptly reimbursed thru Pay Pal. First major problem we've had. It would make 3/4 of a turn and then lock up. Tried everything suggested here but nothing worked. We didn't feel we could afford more $$ for a repair bill as we are hoping to resell some. Not looking for lots of $$ just having fun buying them and fixing them up.
