I would tend to agree with the primary ignition issue. I'd recommend checking for spark, remove plug and place 1/4" or so from good ground and crank the engine. If no spark then check the primary lead from key switch to distributor and internal distributor primary lead to make sure the insulation is good and not grounding. The internal wire is kinda sorta special, many many very fine strand wire that is able to withstand the bending twisting from the lever and plate, Its available from the venders or possibly from local electrical store.

If there is spark and engine won't start, then I'd recommend looking to gas cap and then fuel flow.
