I'm also not sure of the comment that fuel flow checks good. Are you seeing fuel injected in the carb throat when you operate the throttle. Most carbureted cars that have been sitting for 2 months, will probably have a dry carb with all the fuel evaporated out of it. With the low volatility of today's gas - this is pretty common. It takes a lot of cranking to get fuel up to the carb and refill the bowls unless you happen to have an electric fuel pump that you can run first to prime it. Anything much over a week and I take a dispenser bottle and fill the front bowl through the bowl vent until gas starts to dribble out of the idle slots in the carb throat. Then with a pump of two of the throttle it should fire instantly.

But you list a lot of MSD equipment above and any of it could be at fault also.
