Cub cudet with Briggs and straton motor run wide open governor are clear has 200 hours on engine?

It sounds like you're describing a Cub Cadet with a Briggs & Stratton engine that's running at full throttle, even though the governor seems to be working correctly. Here's a breakdown of the problem and possible solutions:

Possible Causes:

* Governor linkage problem: While the governor itself might be working, a problem with the linkage connecting it to the carburetor can prevent it from properly controlling the throttle.

* Carburetor issues:

* Dirty carburetor: A dirty carburetor can cause the engine to run too fast, especially if the idle jet is clogged.

* Malfunctioning carburetor components: A stuck needle valve, faulty float, or a worn-out throttle shaft can all lead to a stuck-wide-open throttle.

* Engine RPM setting: Some Briggs & Stratton engines have an adjustment screw for setting the maximum engine speed. If this screw is misadjusted, it could cause the engine to run too fast.

* Stuck throttle cable: If the throttle cable is stuck or binding, it could prevent the throttle from returning to the idle position.

Troubleshooting Steps:

1. Inspect the governor linkage: Make sure the linkage is connected properly and moves freely. Look for any bent, broken, or worn parts.

2. Clean the carburetor: Remove the carburetor and thoroughly clean it. Refer to the engine manual for specific instructions.

3. Check carburetor components: Inspect the needle valve, float, and throttle shaft for damage or wear. Replace any faulty parts.

4. Adjust the engine RPM: If the engine has an RPM adjustment screw, adjust it to the correct setting as per the engine manual.

5. Inspect the throttle cable: Make sure the throttle cable is free of binding or sticking points. Lubricate the cable if needed.

6. Check for vacuum leaks: If the engine is sucking in air from a leak in the intake manifold or carburetor, it could cause the engine to run too fast.

Important Note:

* Always refer to your Cub Cadet and Briggs & Stratton engine manuals for specific instructions and troubleshooting tips.

* If you are not comfortable working on the engine yourself, it is best to take it to a qualified mechanic.

By systematically checking these potential causes and troubleshooting the issue, you can hopefully identify and fix the problem that is causing your Cub Cadet to run wide open.
