Initial adjustment of airflow meter on CIS 200 1982

I'm having to put back together an airlfow meter on a CIS-equiped 244 that I recently bought. The previous owner took it completely apart thinking it should be cleaned. In the process, he removed the screw that adjusts the mixture. Anyway, Acording to the Volvo greenbook, the

3mm screw should be turned until fuel "begins to flow from an open port on the fuel distributor" and then turned back counter-clockwise 1/2 turn. These are the instructions for replacing the part with another one.

Does this mean that fuel should just become visable in the open port, or should it be flowing out? I know I will have to fine tune the CO once I get it running, but for now, I just want to get it started.

I tried turing the 3mm screw until fuel just appears, but I've still got a no start. The injectors spray when the flap is manually raised and the pumps are on, so I know I'm getting fuel, just not the right amount.

Any ideas?

Well with the engine cranking it pulls the flap open and so fuel is injected. If you are only somewhere near correct it should fire or splutter if not run. Spluttering if its too lean, but should run even if its too rich. You should be able to determine whether it needs more fuel or less.

What you can do is lift the the airflow sensor plate with the allen wrench while someone is cranking the motor. When it starts fiddle the screw back and forth a little at a time until it will idle on its own. Then trim it a little either way until it idles best possible then back it out until the idle starts to fall, then back clockwise a 1/4 turn and it should be happy to start and idle.

Is the movable round disc centered perfectly?

Is it within spec. distance from the top of the bore it rests in?
