Recently re-soldered my Idle Control Unit, which seems to have corrected my high idle. Prior to this, a mechanic made a ("slight") adjustment to the idle - thinking this would fix the high idle (against my advice).
Now with the high idle no longer surging, there appears to be a very slight stumble in the idle (I'm striving for perfection

. I'm thinking its due to this mechanic's adjustment and would like to return it to where it was previously. (Could be vacuum hose, but I've checked repeatedly).
Can someone please post a picture of the idle adjustment screw? I know its somewhere beneath air filter, but dont wanna start turning the wrong screws.
Thanks.
