Well...I hate unfinished threads, so here it goes. I'm here to receive my DA of the Day award. I looked and looked and looked for the damn pug. Couldnt find it, went over to my tools, hoping that maybe I had memory loss and did take the plug out and maybe it was still in the socket. There the damn thing was, sitting on the end of the phillips screw driver that I used to loosen the intake boots. Turns out the oil plug has a phillips head as well as a hex head... I remember thinking that it looked a little different than the other two, but just figured that someone else at jerry rigged it....and the carbs came right out so figured I had loosened all the clamps.
