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??

Thanks... that screw must be in a different spot, maybe underneath. The one on top right didn't do it.

Is your basic throttle cable set correctly in the holder bracket? these have to be adjusted as well. Do not mess with the governor.

Yeah, moving the throttle lever appears to move the throttle arm under the carb through its full range. But maybe I should check it. I think I saw a YouTube video on that... move throttle arm to full, loosen the screw in the bracket, hold throttle arm up fully while retightening the screw?

Don't overlook the governor lever tension springs they are what keep the governor form blindly commanding wide open throttle.

The governor flyweights center push pin constantly put tension on the springs when the engine is running.

I haven't yet found a clear image that would help me find my error. I *thought* I took good pics before taking the old one off, but I must have missed something. Interestingly, if I move the throttle to choke, the bar on the bottom left goes up as I think it should. But when I pull the lever back, that bar doesn't go down. A spring problem somewhere??

Can you add pics of the top. right and left sides of your carburetor with the top engine shroud removed. A distance of roughly 2 feet away should be good.

Here are the three top views and a lower view. I can't see how the spring I highlighted does any good since the rod is inside it. Maybe it should, because if I manually life that rod while the engine is running it revs down just fine. Moving the throttle lever moves the round plate quite a bit, but doesn't move that rod hardly at all. BTW, the set screw on top right does nothing.

I forgot to ask earlier, but can you provide a picture of the engine label information off of the upper fan shroud (if Kohler) (if B&S, the numbers stamped on the top of the valve cover) Husqvarna does not make the engine for their riders. Just documenting them on a reply would be good also.

The spring you need to look for is a little larger diameter and should be hooked to the governor arm behind the throttle cable control section that is mounted on the engine. Likely one end of that spring had come off.

The tiny spring with the long end that you show in the pics only steady's the throttle shaft lightly when at low idle.
