Bill,
It was around 60 degrees farenheit (16 celcius) this morning, and based on the pressure charts, the control pressure at cold start should be in the range of 1.8 to 2.3 bar. Mine seems to be out of this range at 2.5 bar.
If I adjust the WUR control pressure down to within the range indicated cold, will it change the warm setting as well? If I'm understanding things correctly, it seems that the warm control pressure is adjusted at the fuel distributor, so the cold and warm system pressures are adjusted independently, at different locations.
Jdub,
I believe you are correct about the AAR and AAV, and you raise an issue as well. Part #36 is called the Auxiliary Air Regulator, and part #39 is called the Auxiliary Air Valve. In reading information on some K-jetronic sites, I wonder if the AAR is being referred to as the AAV, and vice versa? I can find nothing that clearly explains the operation of these components as separate items, as it seems that AAV and AAR are used interchangeably.
Based on the diagrams, it looks like they work together in some way, however I don't know what each component contributes.
Can anyone clarify what the AAV and AAR do?
Thanks!
Michael
