Enginegoes full throttle on start up

I have a Craftsman rear engine 10HP riding mower
Engine Model 143.98 1002
Family ttp358U/G2EA

It ran poorly when I got it - I cleaned the carburetor
I had the carburetor apart 5 or 6 times, never got it right
I bought a new carburetor - the engine now runs fine -however when I connect the governor linkage it goes to full throttle. I have tried every linkage hole onfiguration with no luck

I know it is a governor or linkage issue
I don't know how the governor is supposed to work
I'm not sure if the spring or linkage was correct when I got it or if the governor works at all. Can anyone get me to the next step. Thanks Pat

RE: Enginegoes full throttle on start up

The numbers you sent are not the model numbers of the engine. There is a shaft coming out the side of the engine that the governor arm attaches to. Loosen the clamp holding the arm to the shaft. Move the carb throttle to wide open position. Turn the shaft clockwise as far as it will go, hold both in this position and re-tighten the clamp with your third hand. :)

IF THIS DOESN'T HELP, then most likely the governor and OIL SLINGER assembly inside the engine are bad. NOTE: And Oil slinger.
