Maybe dumb of me but I didn't even think that they would be different. Inner carbs are 122.5, outer two are 120. I set all the mixture screws to 2.5 turns out. They were all set to 3 except for one of them was 4+ turns, weird. That one was the most fouled spark plug which makes sense. I took the float bowls off (for clean #2) and the gaskets don't want to fit anymore. Looks like getting hit by gas made them expand. No dealer in 100 miles carries them of course even though I have the day off. Dealers don't carry any inventory anymore at all. "We can order it for you!" Yeah, I can do that myself. Off to eBay. The carbs are clean-looking-ish and I think I can avoid the overnight PineSol bath for now. If they were super gummed I'd go that route though.
