What to do?

[wilhelm starberg <wilm@xxxx>]

Hi,

The previous owner of my car installed a brand new Volvo engine a
couple of years ago, I think it is from a 760 - it looks identical to a DeLorean engine.

There is a couple of things done that I find a bit strange:

-The vacuum line between the charcoal canister and the throttle edge tapping is missing.

-There is a vacuum line going straight from the throttle edge tapping to the spark advance
on the distrubitor - the solenoid valve is bypassed.

-The control pressure regulator seems to be a "760 type" - no vacuum conections.

-The thermal control valve is not used.


What is this? should I buy a new CPR and the other stuff that is missing, and make the vacuum 
system "original" again - or should I leave it as it is.
Does not the vacuum line between the charcoal canister and the throttle edge tapping serve a purpose?


Thanks,
