See my reply elsewhereIt's a keeper and allegedly worth £18k. But only if you think it is.
The number is no longer recognised, which could mean it's been scrapped or had a private plate put on it.
End of story.
Using oil catch cans is quite common.
And you can always plug the inlet to the carb.
I am wondering why you talk of mapping an SU carb. Mapping is for chips for ECUs, carbs have to be tuned and set up correctly. Was this just a senior moment?
Yes, told you I knew little about tuning or the correct nomenclature even.Using oil catch cans is quite common.

AFR/Lambda value! ROFL!!!!!!!
Never knew you could do this. Stuff they make nowadays.You could fit a AFR gauge kit they are cheap & the mini doesnt have a lambda sensor.
Yes, these things I do know in theory (and a little practice) but when the car has passed through countless hands and all sorts of carp has been done to the engine, the carb and the cam you do not know the baseline. Using an AFR/Lambda gauge on the exhaust you at least know exactly where the car is over-rich or leaning-out. Mini's of that age don't have a lambda but you can fit one and an AFR gauge.AFR/Lambda value! ROFL!!!!!!!
In the day the best thing you could do with anything you stuck up the exhaust pipe was a CO meter reading.
This is beginning to remind me about the story I heard of the AA man who turned up to a broken down MGB. Apparently he spent 15 minutes looking to find somewhere to plug in his diagnostic!!!
You basically have 4 things to tune.
Rocker gaps.
Points gap (if it isn't converted to electronic)
Timing, (i.e. by rotating the distributor until it is right)
Fuel mixture and tickover setting.
SUs are designed to give correct fuelling across the rev range which is handled by the profile of the needle. Or needles if it is a twin set up.
There must be loads of books you could buy on it. I have Vizards book on tuning the A series engine, but even a Haynes will tell you how to set up a basic tune. And I do know yours isn't a basic one.
Plug cuts are a very reliable way of seeing if the mixture is correct. You can try using a Colortune but I find they only work on brand new SUs as inevitably they wear where the throttle/butterfly spindle passes throught the bushes on the body of the carb, which allows air past them.
Shame you aren't closer we could have fun with this and I have all the old skool equipment necessary!
I find it hard to believe that you are nearly my age yet this is a black art to you. Maybe you drove fords in your youth!!
Indeed!
