This screw, that you see in the picture. When I put an allen wrench in there, this screw is "spring loaded" meaning I can push down on it with the allen wrench and it pops back up. Is this the action that should be occuring? Just doesn't seem right. Maybe you guys can tell me...
The screw you push down meshes with the idle mixture adjustment screw as shown in the pic Pete posted. It pops up to keep you from causing damage when pressing the throttle with the adjustment tool engaged.
Note that it is an idle mixture screw and not an idle speed screw.

I haven't messed with mine as the engine is running smooth. But its still really hard to start unless, while I have the key on, I go out and press down a couple of time on the sensor plate and then hold the pedal to the floor. After I get her started, she runs great, with no hesitation whatsoever.
