And you haven't messed about with plug leads ? Not 1342 firing order.

Sorry if I'm a mile off and you already know this.

Coil? Carb to manifold gaskets gone?

What sort of seal are you using at the carb to manifold connection? , the sort that use "o" rings can cause problems similar to yours if the seal gets blown out or sucked in , just a few minutes work to check?

got it running today, turned out to be the rotor arm, the spare i tried was duff aswell.

thanks for all your hel.

We had probs with the hot rod rotor arms on the 2ltr pinto ( Cost us 2 scottish opens:mad they burn out across the top contact apparantly theres a doobrie inside that does'nt like the high voltage coils that we were using (acording to the guy at the autosport show we should just use a std sierra coil).

sound about right, i've got a flame thrower coil, and the rotor arm has some sort of radio suppression gismo inside it, i'm gonna see if i can find one with the solid copper bit acroos the top that will fit.
