Great job DBLOCK. You're machine looks like it's in realy good condition. If you haven't already, finish lubing all the specified points in the manual. Some are under the machine. That should help improve smoothness a bit more. This link is to the manual: http://www.ismacs.net/singer_sewing_...ine-manual.pdf This website if chock full of helpful info for older machines. You can even look up the serial number to date it.
You've got something that'll last another 50 years with care.

There is a good chance that the wicks need to be removed and cleaned in alcohol to remove dried lube from them as well. Use needle nose pliers to pull them and be careful. You will be pulling on a metal clip that holds a spring and the wick. Avoid deforming the clip and be aware that the spring is attached to the wick and easily bent as well.
Now get back to work and finish the job.
I understand and I'm on it! Thanks for setting me straight...
