Andy,
Peter Baldwin, near Royston, is really very good (01223 207217).
However, I,e found another at Great Gransden- MASS Motorsport. They recently did my 'Black' Enduro car and the result is excellent. The cahrged £67-50 for a full rolling road session. The guy to call there is Chris Conoly and his number is 01767 677800.
I hope this helps,
Peter

No, Autotechnique, who used to be in Kingsway, went out of business several years ago and I have used Peter Baldwin, who realy is the best there is with Minis. He's not all that far from Luton really. Just go out towards Cambridge and go North from Royston for about 7 miles. Acutally a better way is out via Henlow, Langford, Dunton and on to Wimpole on the A603 (which is where he is).
Hello again.
Since the last time i wrote the mini has had new plugs, new cap, new arm and electronic ignition put in the dizzy, this with a little tune up solved all my running problems........Then i went on a long drive and there all back again! Runs very lumpy if it runs at all, any ideas what it could be? Its been feed optimax if that makes a difference??? help needed other wise i wont be able to drive it to the rolling road i've got booked saturday.
(p.s. plugs look a little black even though they are less than a month old)

Is it running at the right temperature? If it's running too cold it can foul up the plugs, which then look black and 'orrible. Try blanking off part of the grille with baking foil. You can peel off bits of the foil as you test it until you get the temp right, then make up a blanking plate in hardboard or plastic that size until the Spring comes with warmer weather.
I had a big problem on the Carpetbagger Rally last Saturday night. My 'S' was fine at first, but with the frezing blizzard conditions in Devon it started to misfire, then this got worse. In the end we lost 10 minutes changing 2 plugs which had foulded up because the temp was far too low. We taped a clip board in front of the grill and after 3 competitive miles the temp guage was up to normal and the running was fine - well, that is until a terminal gearbox failure put us out 30 miles from the end.
So, now I need a complete new s/c, c/r gear set, drop gears, selectors, syncros, etc, etc. A very expensive night's rallying. And to think we were lying 4th at the time amongst the modern cars in our 40 year ols Cooper 'S', even after losing the 10 minutes. Shows just how good the Mini design was and is.

Seconded MAss - superb - I have all my cars set up there - they doubled the BHP on one in a few minutes !
That's not too bad
For a road car you really don't want to go to more than about 90 bhp at the flywheel as it's after that the unreliability starts to show up the limitations of the transmission. At over 90 bhp you do need to consider having s/c c/r gears, a cross-pin diff and, possibly, better drive shafts. The trouble with the close ratio gears is that you then have to drop the diff ratio to prevent 1st being much too high and then you lose top end cruise capability. With 12" wheels and a s/c c/r box you really need nothing higher than about a 3.76 diff or, ideally, a 3.9. Higher than that and the clutch takes a real hammering when pulling from rest. In my Historic 'S' rally car I run 10" wheels with a 3.9 final drive. My engine gives about 112 bhp. at the flywheel and is a bit cammy, so even the 3.9 can seem a bit high sometimes. However, I only pull 14 mph/1000 rpm in top.
The earlier Cooper 'S' and Clubman GT ratios are much better than the later 'A-Plus' ratios, which are not really very good.
