With a chain you can be any number of degrees out, but if you are sure you are timed to 180 or 0 degrees, the only thing that it can be 180 out from is the distributor, check which plug the rotor is pointing at when the cam lobes are down rocking on # one cylinder valves. If you are 180 out you can do several things to remedy it, one remove the leads from the cap and refit as required, or remove the oil pump and dizzy drive and refit drive 180 degrees around, this can be tricky to get right but just takes trial and error. (you will need to remove the dizzy to do this, just check the angle of the drive and judge the off set to be 180 degrees out when you have refitted it (looking from above)).
Sorry a bit wordy, hope you get the idea.
You can remove the cam sprocket by wedging the cam chain tensioner with a spacer, (eg piece of wood the right size to jam the chain against the guides and fit all the way to the bottom sprocket) this can go all wrong if you don't get it right causing the removal of the front cover etc. but can facilitate adjusting cam timing if needed.
Hope this helps, all the best.
Cheers mate, i got it sorted. had to stuff around with the oil pump thing to get the dizzy pointing to the right place and now my engine starts! and it also runs!!
but now ive run into another problem.
the twin su carbs i put on just keep revving without me giving the car any gas whatsoever, it just revs straight up and i need to kill the engine before i do damage to anything. anyone had a similar problem? or someone who knows alot about su carbs?
