New carb revs too high

[ILENGINE]

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.

Looks bent to me and holding the throttle from moving freely like it should

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.

That one is a secondary. the gold yellow colored one below that is the primary.

I replied earlier about the throttle shaft rod... it looks pinned up beside the plastic intake. Was the rod bent on purpose?

 

[BQuirky]

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.

I shy away from all governor adjustments unless 100% needed.

Are you sure the mower is a YTA24V48 and not a YTH24V48
