Hi I’ve just bought a singer 211g 566 that was supposed to be in good working condition well maintained and serviced regularly (not) it’s very dirty and possibly never been oiled since 2012 when last person bought it from a sewing shop. Anyway I’ve had to take apart the bobbin housing shaft etc to clean it but when I put it back in to check timing etc the bobbin housing rubs on the needle ! It did not do it before cleaning any idea how I can resolve this please. Also can’t get hook to 1/16th inch above needle hole as stated in Manual it comes higher up more like 3 16ths but can’t see how it can be lowered as it’s the 566 it comes as a whole unit rather than other models where you can add or remove a washer. Hope you all understand what I mean as new to all this and trying my best to follow old singer manuals and hand drawn pictures. I have other questions but will ask those later just need to sort these issues out first. Thanks
