I have just aquired a 91 example and already love it.
It is running rich, Is this an adjustable item....and where does one find a manual??

Hi there

Try look at the ECU, there should be a potmeter though a hole.

Best regards

Very minor adjustment can be made via the adjuster either on the ecu or there is a small adjuster near the expansion tank. However if you can tell it is running rich it is more likely that one or more of the sensors for the injection system have failed or are giving false readings as the adjuster would be for fine tuning only.
Also consider whether the tappets still have correct clearance as these are often neglected and may need reshimming.
You should also be aware that the fuel consumption round town will be pretty diabolical and is not a sign of bad running.
Should achieve 30mpg on a run.
Though the official manual including turbo suplements is MASSIVE i believe it is possible to get a reprint from
some sources but this does not include the turbo bits and possibly not any other updates(havent seen it to verify). There is a Haynes-style manual available in either french or italian but i cant remember the publisher is quite comprehensive and includes technical data and turbo info

A manual ( photocopy) should be available from the Lancia library section of the Lancia Motor club, uk
