Spark at spark plug when it's unplugged?

[seanb740]

Recently was having problems with the chainsaw not starting ordered a new carburetor cuz it needed replaced as well but now that the carburetor is on there it's still not firing and getting spark at the spark plug when it is unplugged at the other end I don't know it's a Husqvarna 120 we unplug it from the coil and it still gets spark why is this? The coil is firing all the time the only thing that is connected is the plug wire and still sparks! What has happened?

The other wires are for the kill switch.
It will be firing all the time with these wires disconnected.
When connected and the switch in the off/stop position spark will stop.
BTW please add some full stops to your question,makes hard reading.
