Just a bit of an update.
Been using the car locally and wasn't running the best. Took the carb off and took the top off the float chamber.......yuk! Very brown and grungy! Unable to get any carb cleaner locally on the day so a cheap bottle of coke came to the aid. Ran a little better afterwards.
Week or so later still not great so checked the timing, bit of a tweak and a bit better again.
By this time though discovered we had a water leak or leaks!!
Bought silicone hoses and fitted. Son helpfully pointed out that this job would have been much easier when the engine was out!

This shot shows without the top hose as I was confused as to why the clubman one was longer and this hose didn't appear to be leaking. The lovely little bypass hose was also changed.
We then went to the Mini show at Stanford as that is relatively close to us. Still had a water leak and suspected it was the top hose as it was wet. Exact location of leak was hard to trace as water was hitting the fan and going everywhere. Making a nice mess of the engine bay!!
Anyway bought a cheap hose at the show and fitted that. Also learned that Clubman radiators are slightly further away from the block hence they have a longer top hose.
However still had a leak????
Further inspection lead me to suspect the water pump. So ordered a new one and stripped the radiator and pump out in readiness.
On inspection think the seals in the pump had gone and it looks like water was escaping through the hole in the casting.

And then compared to the shiny new one.

So all assembled and run up to temp and seemed ok. Oh also bought the Clubman silicone hose and Proper clubman top bracket

Then had to go away with work so back Friday night and off to Curborough sprint track on Saturday with my Son as my motor club had hired for the day for a track day.
Longest journey yet. Made it there. A good number of runs round the track and made it back!
Only problems
New wipers are useless. Should have bought the heavy duty ones.
Electrical connection between wiper motor plug on loom and park switch on wiper motor not very good. Lost wipers completely on one run. Not good when throwing it down.
Ride height far too high, meaning no negative camber and coupled with 20 Year old tyres and wet track meant Baldric only wanted to go straight on, Great fun though.
Hopefully be able to get hold of and post some piccies of the track day in the near future.
