Well, you

I absolutely must use a system or I'll forget something, but my new 320k I just attacked with nothing other than the experience of the 319(k also). First thing was to remove the needle and make sure it's a 206x13 (it was). There's just no substitute for experience, and this machine is now as close to perfect as anything I have: it's way smoother than my lovely 319k because I knew exactly what to do. The mechanicals, the motor, the foot controller, all from experience and lots of reading. This one was slightly different in that I used WD40 to dissolve the old dirt and not sewing machine oil. It was very efficient, but I doubt I'd do that on an older, Japanned machine. WD40 is (apparently) 51% Stoddart solvent and goes through the brown caked on crap very quickly (checked the decals carefully and seem unaffected)
We're so lucky there are so many quality and other machines around so we can all learn without too much risk or expense. The beauties in our collections must "run out" at some stage and we'll be the repositories of experience.
Just a few morning thoughts

One more machine to go over this weekend (the 401g).
