I think my Farmall H is set a little to rich because when I go to start it I give it 1/4 throttle and no choke and It fires right up. Also, when I pull back on the throttle, I get a puff of smoke then it clears right up. My question is, if it the carb is set too rich , which screw should I adjust? Thanks!!

Leave it alone. The "black smoke" is more noticable with todays cheaper gasoline.

That's the way an H is. Leave it alone.

With the engine warm & running at wide open throttle (WOT), turn high speed mixture screw (on the bottom facing down to the rear) in until the engine begins to starve for fuel. Then turn the screw out until the engine begins to blubber. Now find the "sweet spot" in between the two settings. If you are working the engine (plowing, etc.), then the high speed screw needs to be turned out 1 turn or more beyond the "sweet spot" to be sure the engine isn"t starving for fuel and can develop its rated power.

The same procedure can be followed for idle mixture with the addition of the ldle stop screw (just to the rear of the governor shaft tube) to set the low speed RPM.
On the "H"& “M” carb, the idle mixture screw (faces to the front just below the idle stop screw) is an air adjusting screw so turning in will richen the mixture and out will lean the mixture.
Repeat the procedure again to make sure “all is well”.

As long as its not putting out black smoke all the time I would just leave it as it is. Most people would love a tractor that starts with out haveing to choke it and if its running good leave it alone. Sort of the old saying if it isn't broke don't fix it thing. Now if you just plain have to mess with it you adjust the screw the sitting the lowest on the carb, but I will warn you if you mess with it you will probably kick your self for doing so in a week or 2
