Thanks Rob. I expect the place to locate the dam would be at the bottom end of the runner near where it attaches to the sump. Fairly easy to get to and make changes. I've also thought about putting vanes where the tube comes up from the carb and branches out to the four runners. The dam in the runner would be much easier to adjust during experimentation. > A trick I learned from an old auto racer, years ago, was to balance > the fuel flow in the manifold by gluing a popsicle stick dam across > the bottom of the intake runner on the richest cylinder using metal > epoxy.
