Lots of people drive themselves crazy trying to determine is it Fuel or is it Spark. This is totally a no brainer if you use Starting Fluid. You take the air breather off, spray a few squirts of starting fluid down the carb and try to start it. If there is a pretty good 'run' for a few seconds, its fuel. Now you can diagnose whatever is happening with the fuel lines. If there is absolutely nothing, its spark. Now you can concentrate on the coil, dist, etc. Hope this helps. It sure helped me!
