ht leads and coil packs help?

[owen33]

helping with a nc29 rebuild and got to re wiring the coil packs and ht leads.
could anyone tell me which wire connects to which from the loom?
we had it yellow/blue on cylinders 1-4 and blue/yellow on 2-3
We've tried loads of different combinations but no luck other than one time but it only idled for about 10seconds.
it backfires, spit flames but doesnt start
anyone have any ideas?

you should have black and white for 1, yellow with blue trace for 4, black and white for 2, blue with yellow trace for 3 hope this helps
