Did a Compression Test on my Mini this morning.
1. 161
2. 165
3. 178
4. 175.

Spec of engine as far as I know (trying to get more details from a previous owner) is that it is a 1275 Metro engine, 1.5:1 rockers, fast cam (unknown which one) and the 9 stud 12g940 head has had some work and may have been skimmed. HIF44, K&N Cone filter. Plugs look a good colour which I replace after it was struggling to start every time.

Within 10% across the 4 so fairly pleased. Maybe look at getting a proper tune and set up and Dyno to get everything okay and find out it potential. Hopefully the previous owner will get in touch soon with a more detailed spec so I know exactly what I have.
