Bosch Mono-Jetronic

[Wouter de Waal]

Maybe this is not the right place to ask, but I'm taking a chance that 
some of you out there has experience with the Bosch Mono-Jetronic. I'm 
thinking of fiddling with the one in my wife's Uno, since the car has 
trouble starting in the morning etc. The local agents say that the thing 
can't be set, but I've noticed that :
1. There's a (tamper-proof) set screw that opens the throttle butterfly 
(like an idle speed adjust) This screw is not touching the control arm at 
all, which can't be right.

2. There's another screw that adjusts just when the idle switch is activated.

Now the question is, how do I convince the computer _not_ to adjust the 
idle speed, so that I can set the butterfly up correctly? Can I just 
unplug the idle switch? Secondly, I assume the idle switch has to be 
_just_ closed at idle.

Any thoughts appreciated.
