I have a 725 Suburban and understand that my governor (which is apparently inside the engine) has come apart?

I'm having a hard time finding a mechanic that wants to work on it.  Any suggestions on getting the part?
Has anyone experienced this?

 

Thanks in advance for the help.

What leads you to believe the governor has failed internally?  What are the symptoms you are experiencing?

I'd work on it if you care to bring it to VA.  But like New Canadian said, what happened that makes you think there is a problem?  There are a lot of things that can happen.

 

It is something you can do, too. 

 

Tell me the model-type-code of the Briggs engine, assuming it is Briggs.

I had a mechanic look at it as it will try to run away. He messed with the springs and could not get it to govern. Took it to another small engine guy who did some similar spring replacing and could not resolve the problem.
That's a very nice offer, but va is too cold (and too dang far) this time of year.
It is a model 19 Briggs. Type 706051

Both mechanics seemed to think that the internal governer was broken

Okay, so it isn't the springs.  Do a visual for the obvious stuff, like is the lever connected to the throttle or has the rod gone missing? It could be as simple as the governor lever come loose at the governor shaft or something binding in the mechanism.

 

Does the governor lever move when the engine is running?  As RPM increases, it should move in the direction that closes the throttle fly (is your fly still attached to the shaft?).  

 

Not to doubt 2 mechanics, but if there where broken governor parts rolling around inside the engine when it was running, you'd likely hear it.

I will take a gander at it to see.  Unfortunately, I was not present when either mechanic was messing with it so am not sure of the operation or if there was any sound that could indicate that it has come apart in the motor. 
Thanks for the tips and I will be back soon.

How mechanically inclined are you? It wouldn't take much to pull motor out, pull off the pan and flip it over and check.

It's kind of hard to epxlain, the governor is like a disc with a rod on it, then the disc has 2 fingers to say that as the motor speed it ,the fingers fly out or open. Once you get inside, it would should be pretty obvious if it broke.

I could likely take the motor off, but would rather have someone more mechanically inclined than myself. 

It appears all springs and levers are in position.  I can move the lever back and forth 1/8" or so?!?!

1/8" is about right.  They don't move far.

Well---I have confirmed that the governor is the problem.  Anybody have one laying around or point me in the right direction on finding one??
Thanks

I think you will want to open up the engine and visually inspect. Make sure no other parts are broken.
As for parts, several of our site sponsors can help.

Well, engine was opened and inspected. Replaced governer even though it was visibly ok. Put all back together and it still runs away. Any thoughts?
