This afternoon I have replaced the sensors, replaced the water hose that split, and sorted out the slight oil leaks from the extra pressure and temp sensors I added.
Starts and runs OK now.

I think I'll get the garage to sort out the timing, mixture, and idle when I book it in for the MOT. The exhaust has some slight blue smoke but I'm hoping its just because the new engine has been sitting un-run for almost a year and it'll sort itself out. The engine is out of warranty now so I'll have to put up with it anyway if it doesn't

Just need to change the brake disks and calipers first. Hopefully I can do that in less than a year and not have to have extensive help from here

Thanks for all those who helped, and anyone who was rooting for me.

Mike.
