Anyone have any experience with the Fish carburetor- M1,M2, or M3? I see them for sale occasionally, and wondered if they really work as legend claims they do (30% more power, or 30% better mileage). Chrysler used the concept of flowing a thin film of fuel over the throttle plate, and shearing it off the edge in their central fuel injection system during the late 80's, so it obviously worked to some degree.
