FWIW I only posted the reply in case someone wanted to hook the springs up properly, changing the control bracket isn't an option for most people.
I originally had a problem with the engine hunting at idle but couldn't find an answer anywhere on the net.
I finally figured that the idle spring needed a slight bit more tension and bent the tab to raise the idle speed and the problem went away.

I do believe that the 98892 after year 1996 have the 2 spring setup, B&S removed the manual idle screw on the throttle bellcrank and added in the idle govenor spring to increse the idle speed.
The only way to adjust the idle now is to bend the tab where the idle spring attaches too.

The way sparker installed the idle spring to the tab is incorrect as he has constant tension on the spring causing it to be on with almost full throttle irrespectively of the controller position.
The way it is meant to be installed is there is only slight tension when it is the idle position

Andy, B&S call the system that has the idle speed controlled by the governor instead of the idle stop screw, "governed idle". I agree that if you have a governed idle engine, you can't delete the feature without providing some form of idle stop on the carburetor, if it doesn't already have one.
