And then find someone with a dyno and run it to see what you are really getting.

To echo what many have already said, get the entire car sorted before working on performance upgrades. Consider starting with the suspension system. “The Importance of Suspension Tuning”

What is the end result of what you want out of the car? To some people performance upgrades are simple and an exhaust system,and upgraded ignition system and they are happy. Are you bored with the power it has and want to make wuite a bit more ? Or do you just want it to be a little more responsove?

and bleed the brakes if you have a soft pedal.  Getting the air out will bring the pedal to the top.  You don't want to be going fast and not be able to stop.

one most notable improvement I made to my 1275 was installing an ultra light flywheel.

+1 to what 6464s wrote - get to know the car (not just the engine),
If you are on good terms with the seller, ask him/her what they know about it. Don't go adjusting things until you know all about them,

- Is the engine original to the car or is it a transplant. You can do that by writing down the engine number and looking it up (there are resources here). For  1973, the engine has almost certainly been replaced, or at least rebuilt. Post the engine number here and the experts will help you idnetify what you have,
 - You say it has dual SU carbs. That suggests to me that previous owners have already worked to improve performance. A stock Clubman would likely have been built with a single carb.
- With dual carbs, you won't have a stock intake manifold, or a stock exhaust manifold. That would be two more upgrades you may already have,
- A stock exhaust manifold is almost always replaced by a header, which almost always goes with an upgrades - tuned - exhaust system. Check what you have.
- Back at the engine, have a look at the distributor and coil. Find out what type you have. If the intake and exhaust have been upgraded, the spark will likely have been upgraded as well.

Post pictures of your engine, your carb setup, your distributor and coil and your exhaust system so people can help you identify things.

Before you start buying unnecessary bling, learn about your mini. Wash the engine. Do a compression test. Check your timing. In the dark of night check for electrical leaks. Once you do all that, you might want to try to make sure the carbs are in sync. Then check back with us and report your findings.
