Don't quote me on this but i'm sure she would not run at all on 2 cylinders. On 3 it would be rough as, but 2 would be a non-starter - I think.
It'll start with plenty of my foot!
It was the leads, it now runs sweet as, my brother came round and he had always taken it to a legitimate trusted garage and had problems with running/starting for a few years (but he only does small journeys) guess what the garage had put the leads on rptating the wrong way round!!!

I copied a picture of an engine off the net.
I tuned it all up with the new supersprint exhaust (the timing is still a little out as it was getting dark) and OMG it is sweet as now, my brother took it out and says its transformed.
He now wont let me turn it into a race car, so guess i'll just drive it around.
id still appriciate a copy of the official layout though please so I can be sure its right.
