Have you checked the fuel pressure? You said that you're running an electric pump so I'm guessing that you have a regulator also. There could be a problem with the regulator and it's sending too much pressure to the carb.
Cutting the fuel supply and seeing how it acts about it will point out any of these problems.
Then being sure if it's an over fuel or under fuel problem will tell us where to go from there.
Ok, trail beast. I started it last night and warmed it up to about 130-140 deg. It is running fat, like burn your eyes and stink. I cut fuel pump for 30 seconds, I could watch the fuel level in the bowls drop but nothing changed with how it ran.
