UPDATE:
A significant amount of "discretionary spending" has occurred and the Mini has been on a rolling road dyno.
The brief I gave the tuning shop was "fed up messing around and poking & hoping in the dark....sort it for me please".
They did.
It now runs very nicely (still noisy in the cabin) but no more pops & bangs, just exhilarating fun.
What did he find wrong?
1. Incorrect coil (he reports that it had a "points" style coil on there instead of one suitable for the electronic dizzy). I never knew there was a difference in "type" just in primary winding resistance and whether the coil needed a balance resistor or not so the one in there was correct AFAIK. So he changed the coil out.
2. Std "Stock" SU BDL needle mis-fueling very badly so he created a custom needle to suit the engine at all rev ranges and loads.
3. Rolling roaded to get the performance figures and tweak the needle to get the best performance and AFR figures across revs & loads.
Dyno reports says 62BHP Max @ 5129RPM and max torque of 72.6 lb/ft @ 3276 RPM
That's not too shabby from a stock metro engine (which apparently this is). All the description in the raffle advert blurb is/was really hogwash; NOT a gas-flowed expanded cc head, just standard, not a "lumpy Cam" just standard.
So the results are pretty good and I am not at all unhappy. It is a nice fun driving experience.
