The throttle on B&S will choke the carburetor. It won't rev up the engine.
I don't see the governor arm moving when I move the throttle.
Governor arm will move if I move it with my finger.
The governor spring is attached to the throttle like it should be.
The springs from linkage to carburetor is in place.
The last picture shows the governor/throttle springs, and governor arm.

With my throttle I can choke the carburetor but that is it. I can't run motor slow or fast with throttle.
When throttle is moved a spring attached to an arm that has linkage to carburetor isn't betting control by the throttle.
The arm that is attached to motor will move but not by the throttle.
So why isn't it?
What I wrote isn't the correct terms it kind of like me saying thing me bob or other stuff.

Hard to say with that little information. But it could have a missing spring some have multiple springs. Can you manually rev it up?

Hello Just Don,

Is the throttle cable held tightly by the clamp.

Worst case is the throttle shaft broke inside the carburetor, or the screws have come out of the throttle plate.

We need some information from the machine label and the stamped numbers on the engine valve cover or top air shroud. Snapper made millions of mowers with B&S engines.

Attaching a couple of pictures, would be a big help.

Help us to help you.

Thank you. Yes, I had to adjust the throttle cable because it wasn't closing the choke enough to start.

It won't rev up by the throttle. I"ll try to do that.

Yes, I had to adjust the cable for it to close the choke all the way.
I just rebuilt the carburetor so every thing there should be okay.

Glad you got it figured out.

NO, I haven't figured it out yet. It still won't rev up unless I push the governor arm with my finger.

Thank you all this forum is real helpful.

did this start when you rebuilt the carb? If so go back over your photos and compare them to how everything is hooked up.

Check to make sure you put the gov rod in the correct hole.

Does the governor spring stretch when you move the dash lever to fast?
Recheck you put the governor link (governor to carb) after you rebult the carburetor.
From the issue you state it sounds as if the governor spring is unhooked or is not being stretched when the dash lever is moved.

well does throttle work now ?

Is this a fixed governed speed engine? That tab where the spring is connected to, in the picture of a picture, is bent over.

You said it will speed up IF you move the governor arm. Correct? When you open the dash control does the governor arm move to open the throttle? When the engine is stopped the faster the dash control goes should apply more force trying to open the throttle plate. If not there is an issure with tyhe governor spring or the control is not working or broken. Remember the speed is controlled by the balancing of the spring against the internal governor. So when you move the governor arm to speed up (engine running) it should speed up and you should notice a stronger force trying to slow the engine. If the governor linkage does not control the speed you may have a broken throttle shaft or the screws have come out of the throttle plate.
