MTD running too fast

Hi everyone I just trash picked an mtd 20 inch yard machines and the engine while I got it running it's running too fast. My normal mower has a carb with adjustments on the side with a bowl, i don't see that on this one. What can be done to slow it down? Also when pulling the starting rope out an clicking noise is heard.
This is a briggs and stration model- 98902 1607 B1 02090554

Under the air filter you will see a spring connected to a tab towards the front of the engine. Bend this tab back towards the handle to decrease speed, or towards the front to increase. The governor vane could also be stuck, or the wrong spring in place, etc...

The clicking noise is probably the blade hitting something under the deck.

Thanks for responding cheese
Is the governor vane you talked about next to the flywheel?
The springs are not that tight at all.
Also the clicking from the starting rope has a mechanical noise to it.

There are so many things that could be causing either problem. You'll have to look and see what is keeping the throttle held open, and listen to try to tell us more than just a clicking sound from somewhere. Under the deck, in the engine, under the flywheel shroud...etc...

The vane is beside the flywheel and the click could even be from there.

I got the mower running at normal speed now. What I found out was the plastic piece that holds springs and the governor together was pushed past it's safety stops. It still takes a small shot of starting fluid while cold to get started the first time even after three pushes of the choke. I took the engine housing off to look at the air vane and after back installed the clicking stopped from the starter rope.
