Finally, the engine problem has been resolved.
Took it out for a spin, and jesus christ it was good!!!!
There was one problem, I broke down on a dark country road. Complete loss of power to the engine.
I thought the timing belt had gone or something.
Opened the bonnet, I could smell Petrol, pipe had come off.... phew. Popped it back on (properly) and drove home.
I now can't wait to go back out in it
I MUST get a Mk2 now.
So, either someone did the timing wrong, or someone tampered with the engine to make the engine not perform well and cause me an absolute ball-ache.
It's took me about 5-6 hours to fix the timing, jesus, what a job.
