A MB mechanic (60-mile away) had removed the original air Flow Meter Adjustment tower because the adjustment allen wrench screw was stripped(?) and he could not make mixture adjusts, he said. After the removal he made the adjustment to the internal air mixture screw, but the car has never run correctly (idle hunting/stalls). So I bought a new Air Flow Meter Adjustment tower and installed.

Unfortunately while make slight adjustment both clockwise and counter clockwise, trying to get the engine to run correctly, while writing down each adjustment, a gust of wind came though and the piece of paper I had been using was gone.

The question? When you have no idea what the correct direction and number of 1/4 turns are needed to get back to where adjusting screw should be, HOW do you start from scratch and get there? Example; with a normal carburetor you just bottom out the screw and back off, say, 3-complete turns. But I have seen nothing close to that concerning the Mercedes.

There is no Mercedes mechanic for 60 miles and that one already cost me over $500 to only have the same problem, and the next closest one is over 125-miles away. And of course the car is not starting now.

So I have to do the work myself, and only have the basic metric tools, and a RPM/DC Volt/Ohm meter. Any suggestions will be greatly appreciated.
