Could very well be fuel bowl level or another carb adjustment. The manual for the H carb I have lists the float height as 1 53/64, so you're off by 3/64 inch--not sure that is significant. If this is an H is should be the "D 10" carburetor. Could also be a clogged fuel supply. With the fuel on at the tank, you should be able to open the drain on the carb and get a steady stream of fuel flow out. If it only dribbles, there is a clog in there. That carb also has an idle air adjustment--the screw at the 9 o'clock position as you look at the carb. This is turned out for more *air.* The main jet at 5 o'clock is opposite--out is more fuel. Turn this in "in" for less fuel, but turn the idle screw "out" for less fuel.
I have an H and have rebuilt the carb in it but never had the problem you are describing. My H did have a manifold air leak. Your carb should also have some sort of filler in the little hole at the bottom. You should not be able to see up in there. I think the filler is some sort of felt to allow excess fuel to drain out. Congrats on getting it running if only for a little while. Fine tuning from here.

As with many things there are often several right answers and a few wrong ones. Some purist I'm sure will disagree to no end with what I will tell you but most of us out here in the real world don't really care do we ? Some of them only bring their noses down out of the air long enough to look down them anyway. If you are like me you are only doing this old tractor stuff because you enjoy it. You
