Briggs 650 series running rough

Why is my lawn mower running rough ?

It's a Briggs & Stratton 650 I/C series engine, 190cc.

I've posted a YouTube video here : https://youtu.be/2ZSbo5Ihai0

In the video it's running at full throttle but isn't developing power and is running rough.
I have found that by pulling on a small spring it will run much better.
I'm not sure if this is a choke or throttle control.

The assembly that moves that the spring is attached to looks like it might be bent a bit, but it doesn't appear to be enough to cause this problem.

Any suggestions would be most welcome.

Thank you
