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??
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?
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.

Part of the issue maybe the bent throttle linkage in your second picture next to the red arrow. That linkage rod should be straight. So I am sure that linkage is binding on the intake manifold. If that rod was straight the throttle would probably be at idle. LInkage needs straightened or replaced and governor static adjustment needs reset.
I didn't get any single picture in which the whole writing was visible because of the angles/lighting. Putting them together (B&S) I see Model 44N877, Type 0003G1. I attached a picture showing the spring I think you're talking about, which looks to be firmly connected.
I prob bent it accidentally taking the carb off. It's straightened now and is not binding in either the intake or the fuel hose. Messed up something else, though, as moving the throttle lever doesn't move that throttle arm.
Be sure there is no "governed idle" spring on the governor arm. If you manually move the carburetor linkage will the engine slow down?
The governed idle maintains a preset speed and is used when the engine is idling and you engage the deck or move the mower it does not stall. It is adjusted by bending the anchor bracket of the spring
Governed Idle Adjustment
Perform adjustments exactly in order shown.
1. Move equipment control lever to SLOW position.
2. Hold throttle lever against idle speed adjustment
screw and adjust idle speed to 1200 RPM, Fig. 22. Release
throttle lever.
3. Bend governed idle tang to obtain 1750 RPM, Fig. 23.
4. With engine running at governed idle RPM, bend
throttle restrictor tang so that tang just contacts governor
lever, Fig. 24.
FWI: Before removing the carburetor, mark the throttle cable on both sides of the hold down clamp. By doing this, you will be close to factory settings when everything is buttoned up.
What I see is that the throttle cable seems to be too long towards the carb. To adjust the cable, disconnect it from the holding clamp. Set the throttle lever knob(on dash) to full choke position. Rotate the throttle control disc to the max CCW position, remove any cable slack between the disc and the clamp and tighten the clamp. Verify the throttle lever moves to both max positions.
