Idle screw?

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...Idle screw?-dsc01646.jpg

So, in theory, that screw could be adjusted to a point where the car wouldn' start. Or is that simply a screw that adjust the fuel/air mixture?

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.

If it doesn't fit, force it.
If it breaks, it needed replacing anyhow.

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.
