That's not a fix but a band aid fix. Shouldn't have to tie up the governor. Now you have a governor that can't work properly and regulate the engine speed as the load on it changes. You will eventually see this when you start placing a heavy load on the engine cutting tall grass and the engine peters out.
Briggs help please.

Mine started sputtering after 10 minutes or so. I unscrewed the gas cap and it would fire right up. If it dies when hot Briggs&Strattons says it's likely a bad coil. You could check the gap which is supposed to be seven thousandths or roughly the thickness of a business card. My mower mechanic told me that the 6 hp briggs&stratton which were made in Canada also have issues with either the intake or exhaust valve but that tends to be on high hour engines. I'd start with a new gas cap.

Before you replace the gas cap: does it run normally with the cap loosened, as mentioned above?
More to the story. This mower had 2 stroke boat gas ran through it by the last guy that borrowed it. Exhaust and spark plug were very oily. I held the governor open to keep it running for a while. Smoked like crazy but got better the longer it ran. I killed it and let it set awhile. I cranked it up and let the governor work on it's own and it surged a little bit at first but the longer it ran the better it ran. I don't know if it was all that oil in it or what but it's running a lot better.

That’s a huge piece of the puzzle to leave out
I don't think fast these days as you've probably figured out.That’s a huge piece of the puzzle to leave out
Like going to the doctor and not telling them you feel poorly.That’s a huge piece of the puzzle to leave out
Sounds like a low idle circuit blockage. I know you changed the carb.
How olds is the gas? Sorry if you’ve already posted that.

you need a new carb! look on ebay they will have a cheap knock off that can get you closer to a good running the way it should Briggs
Changed the gas to straight gas after changing carb. Its running ok after we got the 2 stroke oil burned out of it.
Just an update. I mowed my yard with this mower. I adjusted the governor and that helped a lot. It's not 100% but the grass was a lil damp and it's set to mulch. I'll try it when the grass is fully dry and if it's still not 100% I'll check the new carb jets. There was so much oil in everything there may have been enough in the fuel line to partially plug the new carb. Thanks all for the help.
