Sorry, it came stock with the falkon ignition. The falkon boot had a loose fit which caused rfi and skipping. Also that ignition drew quite a bit of current, I think it was about 1.6A at WOT. I sent the engine to C+H out west and had the falkon replaced with a C+H ignition module.The C+H unit draws considerably less around 500mah +/-. I am very happy with the engine overall, but did not like the Falkon ignition. The engine and muffler weigh in @ 27 oz, the ignition module about 4 oz, and a 1450 mah 4.8V around 4oz = 35 oz.
