The worn gears, while certainly not a good situation are probably NOT the reason for poor governor response.

Check that the governor weights pivot freely without too much play in the pins. Make sure the "fingers" on the weights that contact the thrust bearing are in good condition, without obvious wear, or a "flat spot". Make sure that the little needle (or ball) bearing thrust bearing is in good shape, and all parts are present there. Look at the diagram: (parts key #24 and #25)

Is the spring in the governor the correct one, and is is it good condition (not severely rusted, or stretched)?

Make sure the linkage from the carburetor to the governor is properly adjusted. Basically, the carburetor butterfly shaft should reach it's "wide open" stop just before the governor lever reaches the end of it's travel in the open throttle direction.

A clogged air intake system, bad spark plugs, spark plug wires connected out of the correct firing order, clogged fuel screen, or carburetor problem can also make the engine have a lack of power, and make it seem like the governor is not doing it's job, as can late ignition timing.

Also, these tractors are not "powerhouses" under the best of conditions. Are you mowing grass taller than what the machine can handle? Are the blade(s) sharp and correctly installed?
