All the plugs are indexed, as close as I can get them using 12 new plugs (8 installed). The electrodes are all in the upper 120 degrees of each hole. I don’t have a clearance problem anyway.
I removed the BG Carb. to put a kit into it and clean it up. To my surprise, I had 88 square jets in it. I had thought it had 89 front and 88 rear. My EGT was 1342 degrees F. It would have been a little lower if I had had the 89/88 jets that I thought. I am going up to 90 square. That should get me in the 1250 range and possibly bring the MPH up some and maybe the ET too.
