RE: Eletronic engine syncronizer **SUPPORT **
Murphey,
You hit the nail on the head...this is definitely spark noise getting into the sensor wires. A local guy had the same problem. The G20ei and G26EI have more noise than any other engine I have seen - plus the ignition pulls about 2.8Amps rather than the industry average of about 600ma. My first recomendation would be to replace the ignitions (C&H for example). You are on the right track... screen wire around the ignition module too...I have wondered if bigger caps on the rails would help too. If you don't have any luck with shielding let me know and I will trade you for a unit to try with more caps on the rails.
