422707-121401 sump gasket

[McTurff]

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!

Thanks wasn't sure that one in the hole was a fastener!

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

Check the throttle plate and make sure a screw has not come loose. I've seen it happen a couple of times. The throttle blade gets wedged in the bore. The screw likely got sucked into the engine and rattled around between the piston and the head.

Throttle plate functions and good!
But dose not move with Throttle control
Will only stay at WOT
should the Throttle plate open and close with Throttle control when engine off?
Or is it controlled by the govenor?
Meaning say on my OHV engines the Throttle control opens and closes the throttle plate or butterfly freely!
This is my first opposed twin so its messing with my head but just working through best I can!

Is the governor arm pull back spring in place?

Yes all springs in place and correct i have looked at every picture on net and manuals looked at every video I can find and tried everything that's why I'm still thinking its the governor?
