Thought I’d post this as this guy really does a great job including videos in explaining the workings of DCOEs. I realize most Datsun guys are running Mikunis but they share many of the working concepts.

Pretty decent explanation for Weber DCOE, I think I agree with most of what is said there and the principles are the same for MIkuni PHH carbs.

Very nice explanation. It took a lot of years reading about this to understand it as well as is explained here.
