Hi, i was given a beautiful classic singer 675U1/3 and it was working but stitching at the bottom needed to be fixed. I tried all the settings and eventually decided to clean and oil the machine as per the booklets' instructions. Gave it a couple of days but today only the handwheel turns, not the needle/bobbin. Any advice? I recon i might as well buy a new one as servicing costs might be expensive. Many thanks, Jay

I know this was an old post but would you possibly still have the Manual for that machine? I have acquired one from my late nan and would very much love a copy of the manual as its near impossible to find anymore.

Have you got the flywheel clutch fully engaged on it? I think this is the flywheel inner and outer on the Singers but if you've got the manual it should describe how.

If you want some help to get it going I'd suggest you join a Yahoo group of Singer enthusiasts and ask for a bit of help there, they love their old machines and some members are very knowledgable and happy to share. There is several groups "Singers" "Vintagesingers" or "Wefixit" so you might want to join a couple and lurk around the message boards, there is lots of really helpful info in files and photos too.

It may be that you've got oil onto the drive belt or something really simple - I'm not a Singer expert though and don't know their models real well but there are lots of classic Singer enthusiasts out there on these groups.
