Thanks greatly.

I thought it may be a weak plug so I changed the plug with another new one, then another new one. Unless the whole box if faulty I don't think the plug is to blame unfortunately.

I'll have a play on the weekend and see if the leads have been swapped around. I'll try clean up the contacts AGAIN too.

I know one of the blokes that works in the Caltex at Virginia has 2 almost complete twins in his shed and a 3rd engine. He offered me them a while back but I had too much to do already so I turned him down. I since lost his number and every time I call the service station he isn't there ... A conspiracy isn't it.
