I have to put a new sump gasket and governor in my 422707-121401 Briggs
Engine is off machine and on bench 6 bolts removed from sump!
This thing is on tight rubber mallet not working don't want to damage anything any ideas
Afraid to keep beating on it!

You take the wife's best big sharpest kitchen knife and place the sharp edge on which side of the gasket you like . Then you use the hammer to tap -tap - tap the back edge of the blade . If necessary work around .

Before doing anything more remove the key and bolt. Then take some medium/fine abrasive paper and polish the crankshaft until it is smooth and shiny. Wipe clean with an oily rag and the sump cover should slide right off.

there should be a total of 7 bolts/studs holding the sump on. Check down those deep hole above and below the crankshaft. I think you are missing a fastener which is holding the sump on.

I'm taking a step back and can use some help!
The reason I'm took motor out is because I belive the governor arm is shot and small gasket leak!
I have adjusted and set governor arm every which way and the engine just goes wide open throttle
I can choke it to control rpms and manually adjust throttle but can't get it to smooth out!
So I decided to put motor back on to go over everything again!

Take a heat gun and run it around the two halves of engine case where gasket is.
