Thanks for posting this. My OM603 smokes too much at idle when cold with the alda adjusted (with washers) all the way out. The smoke is due to too much fuel being unburned. But once the engine is warm, it idles clean.

I have been trying to find a way to make the ALDA user adjustable from inside the car, so your post has given me a few ideas. That way, I could keep the ALDA adjusted for less fuel when I first start the car in the morning (to keep from polluting around my family too much), and then once warm, I could adjust the ALDA to provide a bit more acceleration.

Has anyone done this?
