cub cadet riding mower surging

I have a Enduro cub cadet riding mower, and 2 days ago, i had to punched the PTO blade off to avoid an obstruction suddenly, and after that incident, the engine would surge when the PTO isn't engaged. When PTO is engaged, it runs smoothly. I cleaned the carb and it seems good shape, pulled the plug, and it seems fine as well. What else could i look for? Thank you.

What's the Spec number?

Seems to me most likely there is blockage in the idle circuit of the carburetor making it run lean and surge. And when you engage the blades, it runs on the main jet.

Kt735-3076 what is the idle circuit looks like? Is it the wires coming out under the fuel bowl?
 
The idle circuit is the path the fuel takes through the carburetor when the engine is idling or at lower RPMs.
carb in the video is for honda. though.

Sometimes it takes a few good cleanings or even a 24 hour soak in parts cleaner to get them CLEAN.
