Singer 66 tension trouble--perfect going slow, loops fast
Hello all.
I have a 1927 Singer 66 that I purchased and overhauled. Just very dirty from sitting in a garage for a decade. Replaced the ancient motor and wiring, but otherwise the parts were all as I got it
My problem is with setting the tension. After a lot of fiddling I got the tension to the point where I get perfect stitches if I'm going slowly (turning the wheel by hand or just barely depressing the controller) but as soon as I start to go with any speed I get great gobs of thread on the underside and my spool goes crazy and ends up binding on the post to boot.
I'm not new to old machines but this has me stumped. Do I need to replace the tension spring? Am I missing something somewhere?
