Actually,that has just dawned on me that it's the same thing.....The reason i ask is,i cannot see my timing mark under the strobe using no1 but i can using no4 and it's vexed me a little. The strobe is flashing too

Unless it was picking up a signal from another lead i guess....

Thanks anyway.

Check resistance of each wire.

This gets stranger......my mistake on this,but the timing marks are actually lining up on 2 and 3 firing,it was 3 i was using,not 4. That's why i can't see it on 1.
Is there anyway the crank pulley can be put on 180 degrees out? Usually they just have one keyway?

I can't get my head around how else this can happen and the engine still run??
