Rich 1-3, 2-4, lean 5-7, 6-8

Pulled the new Autolite AR73 .035 gap after the 1st and last ride (about 6 miles) after installing them. 1,3 and 2,4 are showing pretty rich but 5,7 and 6,8 are showing real clean almost like new. No wonder the AFR readings in my post #53 are so screwed up. I didn't find anything wrong with either carb since checking them a week ago other than had to lower float level on the front carb just a hair to get the 7/16 drill bit under it as shown in the carb manual. Didn't find any intake leaks either.
Another question, how much will the plugs clean up after correcting the fuel problem and reinstalling them. Can I depend on the reading from them after that. Good idea to clean them with carb cleaner or ?
The plugs in the pix are lined up as they came out of the engine. 1-7 on top, right to left, 2-8 on bottom, right to left. #1 has been lightly wiped with paper towel before I thought to take the pix.
