OK, one more time. Press on the the plunger. It should retract. When it bottoms out, unplug it. Set the gap between the plunger and the throttle linkage to .060. Plug it back in. There is an idle learn procedure after this, but my understanding is just drive it and in a day or two it will learn on it's own. If the idle is still too high, low or erratic, than you'll have to search out the procedure. That I don't remember.
