Check the 3 main things for a carburated engine. Fuel, Spark, and power to the coil. Pour a LITTLE gas directly into carb, stand back, and crank. If it fires and stumbles, It is a fuel related problem. Try holding the main coil output wire- the one that goes to the distributer cap close to a ground and see if you have a spark. No spark, No go. If you are still unsure, take it in.
