You got a service history with yours?
I assumed mine would be in the driver's manual like in mum's rover and most cars i've seen before... checking it out a week after buying (after cleaning it up, scraping the algae off, polishing etc

) there was nowt. All I really got was a few receipts for the last couple of MOTs, a new pair of tyres and some part of the exhaust (didn't do much!)...
Not that it seems to have hurt the car much.. and my own collection of servicing receipts are a bit rubbish.
And as concerns burnouts in a 1-litre - try it. You'll be surprised. Certainly in an injection, as it's got an almost diesel-like quality low down (well, like the gutless 1.4 *VW* diesel anyway!) so even if it ends up being a slow, one-wheel burnout, it'll keep it up. Could even still manage it (just) when the clutch was shot... in the wet!
The max torque for the carb is a few percents weaker and a couple hundred rpm higher, but I don't think it should make a real difference. Keeping it still might be the problem because of the weight distribution and the brakes

the front wheels will spin, the rears *may* remain locked if you have the handbrake pulled hard enough..... and still you'll start moving, probably in a bit of a crablike manner!
And then you may as well go banger racing down the nearest greyhound or motocross track.
