Good News! I had a new d21 champion, put it in and it runs fine. Most of the suppliers I use offer a 386 autolite for this application, the plugs I installed were from an ebay supplier and are 3116 autolites, I'll probably put a fresh set of 386 autolites in it and see what happens. The D21 champions I have are used in my IH "H" which is somewhat of an oil burner, but they work well and have lasted a long time.

Thanks so much everyone for the timely replies, this website has always been so helpful, your time and effort are always Greatly Appreciated, Thanks Again...Tom
