Miragepilot: If you don't have a servo controlled mixture, doesn't your engine go lean as the fuel burns down? I'd like to install this just for 'insurance' against that happening...this engine isn't exactly cheap. I do have one of the K&B remote needle valves and mounting this on one of the top stator bolts would be simple though.
By the way, the builder of the plane put a Sullivan DF saddle tank on the left and a 12 ounce slant oval on the right and both have their centerlines even with the carb. It also uses tuned pipe pressure to the tank vents. We're covered in snow up here so it'll be a while before I can test fly this thing, but I do have to sort out the fuel system and run the engine enough to set the needle valves.
