So it's definitely running very rich. Getting back to your original question ie how to adjust, it used to be explained in the old haynes manuals (maybe in one you have?). You may have to remove anti-tamper plugs to gain access to the screws?, but it's a case of engine at normal running temperature, increase idle speed with stop screw, then adjust mixture to correct - If you've not done this before, it can take some practice, but you'll find if you unscrew too much (ie let in more fuel) it will 'hunt' (sort of cough-chugg), screw it in too far, and you starve the engine of fuel and it'll die fairly quickly. Just get it about midway between the two situation. Step 2 reduce the revs a bit and repeat exercise, keep going until you get no further improvement or your hands get too cold! Verify next time after a run by checking plug(s) Hope that helps, Martin ----- Original Message ----- From: Mark Miles To: [email protected] Sent: Saturday, October 23, 2010 12:54 PM Subject: Re: [Quantum Owners] mixture adjustment.
The plugs come up very sooty, only checked them this week and it was after a trip of about 40 miles.

Hmm..... Strange how it didn't show up on emmission test - although I've been sceptical of MOT equipment for a long while. 3 previous cars have shown zero CO at MOT! That's an ancient Reliant Kitten, a fiesta 1100, and a Ka (the only catalysed one). Their equipment is only calibrated every 6mths. (every day or more frequently is auto-industry norm). Have you examined the plugs after a long run?

It is not as bad but still much too strong, comment was passed by a friend who was in the car behind me about it and that was after I had completed an 80 mile trip.

Thanks Ian, Under the bonnet smells fine, either when running or not. the petrol smell is definitely from the exhaust.

Having gone through the mot ok, the first thing I would take a look at would be all the flexible petrol hoses. They have a nasty habit of degrading over time. Kermit used to stink the garage out all the time until I sussed out that all the flexible hoses under the bonnet were acting more like sponges...
