I received the new case assembly last night and installed it, and no change...it still sticks with the new hook installed. I reinstalled the old broken hook (as well as I could) and with it, everything spins freely, so I think Suzelle was right...poorly made part. So I found a good used original hook that I bought and will try that.

I really hate to call and ask for free help from anyone! Barring anything else, I will drive it over to Toledo! Or just buy a good used one.

I came across a post on another site about the exact same situation on the exact same machine though, so I think I am on the right track, and have hope!

Sometimes it is better to cut your losses on a particular troublesome sewing machine and buy something that is known to be in good working condition. Otherwise, you will end up investing as much in trial and error parts as the cost of the machine head itself.

I agree! I am going to try this last thing: I am going to go over the sticking one with my dremel and a polishing attachment tomorrow and see if it makes a difference. I don't know why I didn't think of it before. Possibly a burr on the outside of it?

I saw an ad for a place selling a new portable Consew CP206R walking foot machine for $499, free shipping, warranty...must say, it's tempting. Do you have an opinion on this type of machine? I am usually a fan of older, used good quality stuff, whether cars or anything else, but as I get older, I seem to be less likely to want to fix and repair, and more wanting to just do what it is I bought the thing for!

To find where it is sticking / rubbing..try putting a very thin coating of nail varnish ( thin with acetone ) or better still, if you have what I know as "engineer's blue" over the surfaces of the case assembly than is in contact with your machine..let it dry..place it in the machine , turn it once or twice by hand..where the varnish / blue is rubbed off..is where it is sticking..and that is where you ( very very carefully use your dremel and a set of polishing felt tips..with a fine cutting paste or jeweller's rouge..) ..might take a few polishes..a few careful polishes and trials is better than one big one which might be too much and remove too much metal..valve grinding paste is too coarse..but diamond paste or jeweller's or polishers paste will do..paint and paste works for a lot of things ;)

wetting your finger tip and running it around the surfaces might also give you an idea where it is uneven..a burr you'll find by running a piece of silk over the surfaces, it will snag on the burr..so will a microfibre cloth..the link that you use for cleaning spectacles or eyeglasses.

Excellent advice , mikesc! I think the dremel kit has a red rouge in it. I have Prussian blue at work for bearings but may be overkill for this. I will be gentle though!

If all else fails take a large hammer to it
