The oil leak is more than likely not your problem. In fact the stator and pick-up coil is oil bathed and even if you looked at the stator you wouldnt be able to see anything wrong. To test a stator you'll have to pick up a manual and (i cant remember exact details) you'll have to check a few voltages off of the wiring harness.

The easiest way to tell if your having electrical problems is to check the spark with a good spark plug against the head.

Remember the 3 things an engine needs: Fuel, Combustion, and Spark.

 

Check your carb boot (the rubber part that connects your carb to the motor). Mine tore in the middle and I had simular problems.
