Literally start here..... How much cranking compression you got? And then how much fire you got.... Desperate times call for desperate measures lol.... Take that lightheartedly but if you have MSD ignition that thing should be trying to weld with a 3/8" gap to a ground... If you have those 2 variable it comes down to fuel and that's just a mist of Starter Fluid just to make it fire off and then you know it is a fuel issue.
The next logical step is timing and there is a great illustration for you in this thread. At 180 out on the dizzy you should have lost some nose hairs if you were leaning over the carb and you have fuel,fire, compression....
Just systematically eliminate what you know is in working order and it will fire.... Look at your plugs also to make sure something is not closing the gap and smell for fuel.
