The idle doesn't really sound all that low to me, but if you can't 
adjust it, you can try cleaning out the idle air passage. The easy 
way to do this is to remove the air cleaner and the intake air elbow. 
Then you can see the opening for the idle air passage. Spray WD-40 or 
LPS-1 in that hole while the engine is idling. That will usually 
flush out any gunk.

Yes, it's missing the shaft that makes it work. You can try to find a 
complete dashpot, or just remove the whole thing. It's not doing 
anything right now, so it's not causing your slow idle.
