8.5 hp Briggs Snoblower Surges then Dies Empty

Ok, so yet again, I've got a busted engine.

It's a 2006 Briggs&Stratton 8.5hp OHV mounted on a Craftsman snow blower.
It starts first pull, and runs ok for a bit. Then after about a minute, it starts surging, and then after another minute, it stalls.
What I did is rebuild the carb, to no effect.

Now the interesting thing is, if I hold the governor at a fixed throttle with my hand, it will run super smooth, and forever.

The troublesome thing it, the carburetor has no adjustment screws, and it has a fixed throttle.

Thanks for any help!

Ho yah totally. It seems to be just a little lean, but there's no way to adjust it. :-/

There's a few things that come to mind. Governor adjustment, partial clog (still) in carb, Bad sels or O-ring or something in carb, Carb vent or fuel cap vent blocked.

The thing is, it runs perfect if you hold the governor at a fixed throttle...
