It's odd how many of these issues solve themselves with cleaning and oiling. Together with a bit of test sewing we pick up minor issues along the way; tension setting, new belts and bobbin tyres... For two weeks I though my 201 was out of timing because the needle scratched one side of the turning part under the race and hook; it tured out the be build up of dirt and grime in the neede bar, behind the needle clamp. I thought I already had the hole thing off and cleaned, but further cleaning solved the problem.
As the decades go by, they often need a few rounds of cleaning, degreasing and lubrication. Cleaning isn't everything, but in the beginning it's a bit part of it. It's very easy to overlook the basic things when fine tuning these old machines. It is a bit tricky to detect exactly wich joint, hinge, cam or gear in a machine is causing the problem, but I guess that's the job we eagerly have taken on when we seek out our favorite vintage models.
