I think everyone a generation older than us will have a good laugh at this thread. I don't even know how a carb works

I'm going with DCOE's for simplicity and a cheaper way to get some better throttle response.
Plus they just sound and look awesome  -Jason |

Yeah, I would think that a wideband and a logging program on a palm or a laptop would go a long way towards removing the "black art" from carb tuning, and might give the kiddies some warm fuzzies as they're not abandoning all their shiny new technology
There are lots of good books on tuning your chosen carb -- get a good one, or two and become intimate with why and how the circuits work and interact with each other. Dave's line, "analog fuel injection" is right on the money -- all you're doing is turning the fuel into an aerosol and mixing it with, hopefully, the right amount of air, no rocket surgery
