Southeast North Dakota
My 8970 used to do that. I ended up taking the pump off and having the governor rebuilt. There was a problem with that for awhile, I don't know if it was a certain serial number range or what, but every now and then you hear of one doing it. It cost like $800 to fix it if I remember right. Good luck!
