So I've owned my Mini for about 6 months and it's kind of been never ending! The performance has never been great, much worse than my old 998.
Currently it's quick off the line, nice acceleration in 1st and 2nd, change up into 3rd just shy of 30mph, then accelerating in 3rd feels and bit flat and "chuggy" and by 40-45mph feels like it needs 4th gear, then slowly creeps up to 50-55mph and that's pretty much all it will give me. On a good flat run, with the wind behind me, I'll get up to 65mph, but put a hill in front of me and. . .
I think it has to be a combination of timing and mixture strength as in the past, when I first got the car, I was zipping along the motorway at 70-75 no problem. But that was before it started falling apart around me :)
Current set up:
Timing's ended up at about 10deg at 1000revs (vac pipe disconnected and hole in the carb plugged). That's done by timing light after reading lots of topics on here, and also roughly where it's ended up after the "advance till it sounds right" and "revs at 2000, advance as mush as you can, then back off until you drop 250 revs" methods. So the two main "feel of it methods" always end up at roughly the same place as where the timing light people say to set it.
Mixture strength. I set the collar level with the bridge in the carb, then two turns clockwise of the screw to richen it up as per general advice on here. I'm currently about a quarter turn weaker than that following the "weaken until it almost dies then gradually strengthen until about right" method.
So as you can see my timing is with 1-2 degrees around where the various advice says it should be and my mixture strength is within a quarter turn of where the various advice says it should be.
So my question is, is my mixture and timing about where it should be? And what else should I be looking at now?
