Righto, me and a mate finally got some spark, but we arn't sure on what leads are what on the dissy. The only dissy cap I have has the leads screw terminated inside the cap (ie. not plug & play). Which lead is which? We think we have it sorted, and have just about got the engine to fire, but I've sorta killed two starters trying.

Nevermind, I've had it run for about 2 seconds. Sounds pretty cool with basically just a dump pipe off the exaust mainfold. Problem was I've got no carby that is good, so I've been using an atomiser spray bottle and spraying the fuel in, but little drips were igniting on the exaust and igniting the inlet.
