I was hoping the ballast resistor was available, but not surprised it's not. I did find a 3 post resistor on ebay that was advertised as for a 240Z and is 1.6 ohms,

so I  ordered that. If that doesn't work out, and I cannot rig the old one up to work, I will be asking for your kludge fix. I am more about function than elegance. Thanks!

Before installing it, I suggest testing it with an ohmmeter.

As it turned out...when I took the Ballast Resistor out, I could see that a stud/post had been sheered off the bottom end (by vibration?) and the nut with it that held on the connecting wire. I simply ran another nut up and down the end of the stud/post to restore the threads, added another nut, secured that wire, reinstalled it and presto - it started and ran fine. Problem solved and after examining the part I received, it looks to be something that should work as a replacement if I ever need it. Thanks to all for the suggestions, especially Steve J.

I now have Seafoam fuel additive stabilizer run through the system to keep it from varnishing up through the winter (though I do start it up every few weeks and let it run for a bit).

Thanks for providing an update. It always helps to hear the resolution for us to calibrate our suggestions.

After you spending the time to try to help me out, it was the least I could do! With the number of these cars on the road slowly dwindling, its great to have a forum like this where owners of old Z cars can help each other out. If/when I run into any other challenges and/or fixes, I'll be sure to discuss them here, so that somebody else may benefit. I have had this car for 24 years and plan to keep it until I am too feeble to climb in and out of it, so I am bound to be posting something again someday.
