1992 190E 2.6 auto

In reading the instructions at http://web.archive.org/web/20060526120023/mb.braingears.com/201_DISK1/PDF/50014.pdf , some wording confuses me.

It reads on page 3...
"Connecting rod(2)...................disconnect. Check if throttle valve rests against idle stop..."

What and where is the "throttle valve" and "idle stop"? Are they pictured/numbered?

Also on page 4...
"Full throttle stop....................check....While doing so, the throttle valve lever must rest against the full throttle stop..."

What and where is the "throttle valve lever" and full throttle stop"? Are they pictured/numbered?

Lastly, I KNOW I've seen an online diagram of the throttle linkage adjustments that had more info on it. Anyone?

THANKS!!!!!!!
