Black smoke indicates too rich a mixture. Lean it out some. That should solve a lot of problems. I think that is right...

Joey:
Will try to explain as best as I can. Use the carb pic below as a reference. It is the Throttle Idle Screw (Part # 2 & 3 - although the screw itself is not shown) that needs adjustment. This is what controls the idle. But to be sure, start at the Idle Adjusting Screw (part #22) This screw should be turned clockwise until it seats, then back it off 1-1/2 turns.
Once this is done, I usually either back off or turn in the Throttle Idle Screw until the carb just about chokes and dies. Then reverse the procesw until it sounds smooth and not to fast. The rpm should be between 400 and 600 rpm, depending on where you Cub likes it. You will be able to tell just by sound when that occurs, cause it will purr like a kitten. I se a dwell/tach meter to set the rpm, then I tune for the sweet spot.
That should do it.... yust me dos centavos mi amigo
Btw, the procedure is in the GSS-1411, which is on the server.

In this parts sketch part 7 the gasket does not show a half moon cut out that is in the gasket. The microfich that my local Case dealer uses doesn't show it either.

The sketch Rudi posted is for an IH carb. I think the Zenith may have the half moon cut out. Is your float a songle unit like in the diagram or a double float? Double float would be Zenth carb.beaconlight wrote:In this parts sketch part 7 the gasket does not show a half moon cut out that is in the gasket.
