To test for spark the old fashion way, remove one wire from a spark plug, stuff a screw driver into the wire boot where the spark plug metal top fits into, lay the screw driver attached to the wire across a metal surface(on engine) that the spark can arc across(don't touch while testing and don't put near a flammable source(i.e. leaking carb on manifold). the engine is negative ground, if the spark plug is getting + juice from the coil, then where ever the metal shaft of the screw driver is touching say a unpainted manifold bolt you should see a park. If you have spark, then things get more interesting, if you don't the problem lies somewhere in the ignition/spark circuit. Have someone crank it over while you look for a spark. Others might have a safer way to do this, or different, this is just the "use what you got" method that we did in High school autoshop in the 70's.
