Tuning S3

[abowie]

What CO% should I be looking for when tuning a S3 E type with Strombergs?

I have a 1975 XJS with this under the bonnet.

In 1975 ADR27 allowed 4.5% at idle. Current aus std is Euro 5, 1g/km

Thanks Colin.

I ended up setting it at 4%. Waiting for the rain to stop so I can take it for a test run.

How did it manage to get carbs on it. Is it a early XJ12 or Etype engine or the original XJS engine with the injection system taken off and carbs put on.

Just an interest question.

Cheers

PO I think.

The only place I recall seeing Jaguar quoting a CO figure for the S3 E is on the underbonnet sticker of 72-74MY emission control cars. Basically adjust if found above 4.5% (with idle timing set at 10deg BTDC, vac retard and exhaust air injection disconnected).
