I'll be over there tomorrow and start digging it out. I have enough clues now to look for thanks to you guy's. Regardless of what it actually ends up being I'm very happy about it. Was last registered in '75. He told me before he passed away that he pulled the carb and put it somewhere in the barn and looks to me like it will still be in there...somewhere. will post tomorrow what I find. I'm gonna go right for that tag under the coil.
