Neill,
I'm a bit hazy on the 35's but give this a try.
Your spark plug leads should go to two seperate ignition coils. You can test the coils by swapping over the orange (from memory) primary wires that come from the powerpack to the coils. If you swap the wires between coils and the other cylinder now has spark you know you are up for a few dollars and will have to test further to see if it is a powerpack, sensor unit or stator. If the same cylinder has no spark you are in luck and it is just a coil.
Cheers,
Mark
