ok kids, so the intake is the original updraft intake. I fabbed a "u" pipe from it and mounted a downdraft carb. She runs pretty good for the most part. The problem I am having is that she runs rich after she heats up. From what I figured, the cause of this is that the fuel is atomizing, then turning back into fuel and pooling in the "u" pipe, thus, making her run rich after, say, 15 minutes. I tapped into the exhaust manifold and plumbed 1/4" copper tubing to the "u" pipe and coiled it around to keep the pipe warm (it gets ice cold and sweats like a pig), BUT, the cold kicks the heat right out of the park! My second thought is to maybe tap into the coolant lines and see if that helps warm the pipe up.
The key, I believe, is to get the "u" pipe warm on a constant basis, as it doesn't run rich until the pipe gets cold and sweats. But this seems to be challenging. Any ideas out there??
