E30 Zone

I've got an M10 engined E21 - one of the last on an A reg, fitted with a Weber carb conversion - can anyone give me an idea where the mixture screw is on it as I've lost the instructions is came with.
Should be same as an E30 one I think, hence why asking here...

Stand on the passenger side and looking from the front of the car you should be able to see a 'sunken' brass sloted screw, you need a small screwdriver, and only half a turn at a time leaving a couple of seconds inbetween turns. Screw in to richen and out to lean it off
Hope that helps
