Hello,

I have a pushmower with a briggs and stratton 3.5hp engine that all of a sudden is causing me trouble. It went from running at a good clip to an immediate drop in engine revs and now it stays at a low idle speed. If I manually move what I guess is the throttle the engine speeds up but it is not doing it on its own. This is the area with the springs and it runs when I manually turn it up but then it automatically goes back to a lower speed.

How can I turn up the gas so to speak and keep this guy running?

Thanks!
