adjustment questions

Farmall C ran great but 5 min after I shut it off the carb would start leaking. I took the carb (Carter UT) to a mechanic who put a kit in it. Now it does not leak but surges up and down real bad if speed up from idle to full throttle. It did not do that before the kit. It doesn't surge if you very slowly increase the speed. Any ideas? I am not sure what to adjust.

My other issue is the throttle lever itself. I have to move it about half way up or more before motor begins to speed up from slow idle. I do not see an adjustment for that. Any help is appreciated.
 
The lever is pretty normal. If the governor lever at the governor is being moved to its full travel when the hand lever is moved to full speed, that is OK. The float level may be a little low in the carb, causing lean conditions. Or there may be a partial blockage in the high speed circuit. Always shut off the fuel when the tractor is shut off to prevent flooding. The gravity feed fuel system can and will flood the engine with liquid fuel. Jim
