Quick Observation: You may want to rethink that Edel 1406. I think your combo needs a bit more carb. I would play around with the other two and see what you come up with. Then you can start tweaking timing a little.
I am sure that the Edel is limiting mid to high end HP, and maybe even low end torque. I hope to test the other 2 carbs Friday night, but am only hoping for 1/2 second or so gain at best.
