Many people through no fault of their own don't know what a good-running H is supposed to sound like. I've watched many a youtube video of proud 4-cylinder Farmall/IH owners marveling at how powerful their tractor sounds and how smoothly it runs, when it is clearly MISSING on two cylinders!
Your H should sound smooth, like a sewing machine, not choppy like a Harley Davidson. After it's warmed up some, you should be able to pull the quickly throttle lever all the way back and have the tractor rev up to full throttle smoothly without hesitation, coughing, or stalling.
If it isn't, you're leaving a lot of power on the table. Your tractor may only be making 1/2 of the power it's capable of. It needs to be tuned up. New ignition parts, rebuilding the carburetor, then tuning the carburetor and setting the timing. Adjusting the valves may help as well.
Of course the engine may be just plum wore out too. A compression check will tell you a lot about that. Much under 90 PSI and power will start to suffer.
