Default Re: Zenith Carb Leak Puzzle

The height of the jets can contribute, if they are too short, i.e. below the fuel level. If the jets do not have a concave surface, they can also leak via capillary action. I had one that was that way and I drilled it a bit to provide a concave rather than convex surface.
