Briggs and Stratton 20 HP V twin Revs high

[rocket9244]

I changed the oil and filter on my mower and was riding it when all of a sudden it started reveing on high speed.
I can pull up on the governor lever/idil and it will rev normal until I let go, then it Revs like a bat out of hell.
What could be the issue?
Can I loosen the screw on the governor and adjust the idil?

first thing the expert repair guys (not me) will ask for is the model number of your engine

Close, but no cigar, ... ( see example ) ...

BUT this should be your engine manual ... ( see section 3 .. page 5 for Governor adjustment )

Numbers are stamped into the valve covers on that engine.

Question is, what happened to make it all of a sudden race like that?
Everything seems to be working right except for the high reving.
If I pull up on the idel it will slow down. But as soon as I let it go, it races full speed.

It's not a v twin . Just a regular 20 HP B & S
