rpm

Newbie here, I put a new carb on Husq YTA 24V48. Throttle linkage seems to be fine, and pulling it back to low does slow it a bit, but not nearly as low as it should be. Is this some kind of governor adjustment, or what??

I have a Gravely ZTR 60. The right hydro gear will not pull at low RPMs and when cutting at max RPM the right gear wines, jerks and stop pulling when making a turn or pulling out of a ditch.

Howdy! I have a 2018 ZT 6000 w/the KT745 engine. At full throttle w/blades engaged, the engine runs smoothly. I do believe even at 3/4 throttle w/o engaging the blades, the engine is surging. I haven't worked on carbureted engines in many many years, so I'm here asking for some troubleshooting...
