I reckon you should change that and the filter, and get the engine hot before the retest
If the oil is old it will be contaminated and will cause high hcs, more so than the mixture.
Are you working this weekend?

Oil and filter changed about 2 weeks ago, air filter 2 months ago other bits (spark plugs, leads cap etc... ) about 2 years ago.
I know the mixture if fubar because if I have it set to run right at idle it runs like a bag of poo under load.
Nick set the CO. etc... at Eurotec last year, and got it to idle smooth as a silk, but the minute you started driving it was a complete nightmare, it kept stalling, stammering under acceleration etc...
The only thing I could do to get round the problem was to richen the mixture at idle, so it ran over rich at idle but fine under load.
Somthing is obviously wrong with the mixture enrichment system on the car, I know all the pressures were spot on when Nick tested them last year, but somthing is clearly not right.
I will dial down the old mixture screw and see if I can get it through.
Any idea on what I should be checking for a long term solution?
