A little known secret about stalling at a stop is an incorrectly ground reproduction throttle plate, or a worn original throttle plate. If the throttle plate does not close properly at the throat of the carburetor to allow the small hole that goes to the idle circuit to just peek above, it will not allow the carburetor to transition from run to idle correctly when coming to a stop.

I had two Zeniths that would stall at a stop after rebuilding them. Snyder advertises in their catalog that their throttle plates have the edges ground to the proper angle as is an original.

I replaced the throttle plate in both Zeniths with Snyder reproduction throttle plates and the problem was resolved.
