740 GLE 1985 2.3 Vaccuum piping.

The engine misfires at low revs, but, put the throttle down and she
flies. A previous owner has messed about with the piping around the
carb and some pipes are blocked off with no indication of where they
originally were connected. I can find no information in the Haynes
manual relating to the piping.
Can anyone suggest a website where I might find this information,
preferably in a graphic format. I have looked on
http://www.brickboard.com/ but can find nothing there.
Thanks in advance.

Hello

I had this problem a while back, and did manage to find a diagram on the
net, unfornately I can't find it again, but you're in luck, coz, I've since
since bought a carburettor manual, I've scanned what I think will be the
correct diagram, and put it on my webserver, you should find it here,
http://82.1.64.66/Pierburg_2b7.htm (apologies if the download speed is slow,
I've only got part of a slow internet connection) if reconnecting the vac
pipes correctly doesn't solve your problem, you might need to check and see
whether the same previous keeper messed around with the idle speed/mixture
settings, and check for air leaks.
On mine, the emulsion tubes near where the PCV pipe enters the air intake,
tend to crud up every now and then, this could also be a cause of your
problem.

Thanks a lot. Next problem is that I now have no excuse, I have to go
and get my hands dirty.
I will let you know if this solves the problems.
