armpit

I bought a 72 RT1 360 with 4800 miles for $120 from a guy that rode it all the time, then 8 years ago, drained the tank and parked it in the shed. It has no key, so he said (from what I could understand) that he was able to get it running by cutting the entire cluster of wires that went to the switch, then just stalling it out to turn it off. I got the carb cleaned, and I am getting fuel and oil into the engine, its got great compression, but I cant get any spark. Wiring diagram: http://www.slimduck.com/rt1360_wiring.htm I tried connecting the red to brown, but still no spark. Any ideas? That dang spark is all that's keeping me from having this baby running. Thanks guys
