Visual Question: What is this lever on my edger carb and what does it do?

I have an old Yard Machines Edger (not sure which year but probably from late 90's) which has been running erratically lately and I've noticed that this lever shown in the photo seems to be related. I appears something has come unlatched or disconnected. And it moves in and out and revs while idling but I can't see any throttle cable. But I didn't think edger had a throttle cable beyond the "Fast/Slow" slider directly above the choke. But it is almost as if the connected cable came undone and got lost? Any ideas what it does?

That looks like it should be connected to a choke. Do you have a choke control?

I think that is usually where a governor spring or linkage attaches. Not sure if you have a mechanical governor or an air vane on that model.

Maybe take the air cleaner off and give us a pic looking down on the carb.

That's the throttle lever. There is a linkage/spring connected to the other end of it. It's not the problem, it is moving because the governor is making it move because the carburetor fuel mixture is incorrect. Try backing out the air/fuel mixture screw some to see if it helps (if equipped. If not, there is a jet screwed into the same spot that may need to be removed and cleaned). If not, it may need a carb cleaning.

To confirm what cheese mentioned, try using partial choke and see if it smooths out.
