Don't know what the tool is called or what it looks like, so I was hoping someone on here can help me. I recently learned that with the 74 or 75 and later Q-jets have an adjustable power piston. In my Haynes book they call it a factory metering adjustment screw on pg 7D-13 (couldn't find it in Doug Roe's book). They can be accessed via a plug on the airhorn. A local circle track racer that Don Eggers knows uses these and adjusts the metering while the car's running. He knocked the plug out, threaded it and put a flush allen plug in. I don't know him and Eggs hasn't seen him for a bit, but I need the tool to adjust mine. I want to try it for drag racing. I was figuring a valve core removal tool would work with some modifacation. Thanks for any help!!
