Easiest thing to do is swap spark cables and points leads at coils - if 1 and 4 stop firing you have a winner.

Points for 1,4 and 2,3 can be either set.

got her running on all four
 turns out it was a fuel issue, sitting for 30 years there was more varnish then I thought
anyway it's on to the frozen front brake caliper.
Thanks to all for the replies
