The Zenith is a direct replacement. It looks a little different, but adjustment screws are in basically the same places and the procedure is the same as for the original carb. However, as Bruce indicated, "the" problem doesn't have anything to do with carb adjustments. If the engine isn't getting fuel, adjusting won't fix it.
