Decreasing idle speed on AAZ after fuelling increase

Is there a way of decreasing the idle speed after increasing the fuelling on an AAZ pump? The idle stop on the throttle lever doesn't have an effect. I only made a small increase in the fuelling cause I felt it was actually underfuelling before but it's giving a nice balance between power and economy at the moment. It's just idling at about 1200rpm so I'd like to drop it back to stock.

Dont know what that pic is from but guessing its from a Yank bok (Bentley?) so guessing its not an AAZ as they never had it, also no LDA.
If you look on the 'head' side of the pump, roughly above the cold start cam/arm , there is a long vertical screw with a spring on it. From memory when i say long its like 4" or so and looks like a dipstick coming out of a sump. Its very obvious. Use this one.
Dont go fiddling with throttle stops etc.
