A governor problem???

Last week I enstalled a new carburetor on my A. I had been having some problems with the carb and the clip that holds the float on had been broken, so I decided to buy a new one. Now the tractor runs very smooth
but the governor will not kick in under a load like it did before. Is there
something I should adjust or look for??

You may need to take the slack out of the gov. rod from the carburetor
