OK, I follow what you are saying now. I had thought that for some reason a G26 glow converted to your ignition was a lot lighter than a gasser that had been converted. I did not understand why a G26 Glow converted would be so much lighter. and maybe the Rim Fire plug was one reason for it. I have used some Rim Fire plugs in some conversions before and I can't seem to get a very long life out of them.
Anyway I will give you a call.
