I am not familiar with this unit, is it elec. start or recoil? If it is elec. start, do you have 12-V at the coil? Looks like it would be a spec. J.
http://www.cumminsonan.com/www/pdf/manuals/927-0754.pdf this link will get you a CCKA engine service manual. Give it some time to down load.
I have # 927-1060 CCK welder parts manual if it will help, I need an e-mail address to send it to.

If you can get the serial number off of the unit I still might be able to pull up the original owners manual for this unit.

First, do what Max said; check for 12V at he coil positive.

It may be that after sitting for so long, the oil pump may not be able to pull oil to build pressure at cranking speed (unlikely) or the switch may be bad (possible)

Try bypassing the "Low Oil" switch by disconnecting it at the coil negative.

give me a little time . Been out of town past few days, A quick note. I still have greenitis but had to modify a 41 year old EK with a 21st century contoller. The good note is I left all the original controls intact and inplace to include the original magniciter circuitry. Will post some pics when I get a moment.

Have you checked the points with a meter. Sometimes points that have been setting a long time will get a thin layer of oxidation that will prevent them from making contact. This oxidation may not be readily noticable.

Your breather valve may be stuck closed. I am working on the same welder at this time.
