I tried the basic setup based on the size of the carb....No worky, so lets go with, they are different. Now I could share my setup, but mine is NA and a single carb...Probably totally different, dunno. I am not a carb guy.

I do know that my AFR is right around 11.9/12.0 WOT....And I need to lean it out just a tad more, and then work on my transition. These carbs idle better and cruise better than anything else I have seen, but I still struggle with the transition which is port #5 I think....

You also have to remember, these uncover a lot of throttle really quickly being what they are...I have called and received tuning advice, and I found the best way is to street it and watch the AFR...Trial and error.
