right, the new crank has an old style taper so the AM6 system is out now Boooo!
So I asked mr Bob and he recons its the CEV mag I need as there are 2 part numbers for ols crank and new.
Guess what, I had a CEV mag originally so after a bit of juggling around it fits. The only issue I have is the key way is different.
Just used the Dial Gauge ( thanks Airhead) and found tdc and had to spin the coils 180' ish and luckily the backplate holes line up with the threads. Just need to buy new contacts as these ones are worn and I will replace the condensor too as I'll rewire the Mag.
Managed to get a spark, so onwards and upwards
