Problems with governor

I have a 2012 B&S (128M02 0115-f1-12020858) with an auto-choke one pull start.

The governor is connected to a lever coming up from the muffler, the lever is part of the one-pull start and run system, when the engine is cold the governor position allows for the choke to be engaged and as it warms up the choke opens. The problem is this thermo-controlled lever position is erratic causing the engine to slow or even stall. When the engine has run for a while the governor position causes the engine to die, manually adjusting the governor will stabilize engine rpm.

Is this thermo-controlled governor part a known issue with some B&S engines?
