308 won't fire

Sorry to correct you WB, but timing marks will line up twice, both times with piston at top, trick is one is compression stroke and the other is exhaust stroke. That's why you could be 180 deg out with dizzy.

Vom, on the compression stroke at TD both valves will be at rest (easy to tell if you've got the rocker cover off)

Thanks Sandaro. Yeah that makes sense as I've got it wrong before and timing Mark has been aligned

No worries. That is correct.
