TROUBLESHOOTING:
Engine will not start: Sometimes the source coil wires are reversed. Swap the connections, re-solder the wires and the engine should start. If the engine still does not start, and before calling technical support, performs a few basic tests:
1) Re-check the connections. Make sure you carefully solder the connections. Twisting wires together or taping wires will cause engine inoperability.
2) Check the engine for spark
3) Is fresh fuel in the gas tank?
If you still cannot get the engine to start, have all your testing information ready for a technician prior calling.
Ensure proper installation by a qualified technician to avoid malfunction.
