I have a 8hp B&S engine and need to replace a spark plug wire.  It doesn't appear to be removable from the magneto.  Do I have to replace the whole darned magneto armature?

Part according to the parts manual:

Anything I should know about doing this, like being careful to get the right gap, etc?

Thanks in advance,
