How to replace spark plug wire -- not removable from magneto?
Original Message   Aug 10, 2009 6:53 pm
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?
<pic snipped>
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,
Kirk

first off by looking at your picture l would make sure your flywheel is rust free and also clean the coil (u can do this with emery cloth/fine sand paper or an sos pad), before u say the coil is no good. but in my experince coils rarely go bad and by this picture l'm looking at theres a good chance its to rusty!!, l assume u replaced the spark plug?, the only other thing it could be is the ground wire has a short to ground some where (bare wire touching the block).lets say the coil is bad than yes u will need a air gap of 0.10. the spark plug wire is not replacable on its own.

That is a good question , I have never seen a plug wire that could be or was replaced. They look like they are glued/epoxy in place. If the wire is bad try to loosed from coil and replace at this point you have nothing to loose. Let us know how you do it .

The coil isn't bad, AFAIK.  The wire end, connection to the spark plug (new plug) has corroded and broken off, so I need to replace the wire.  As you and whitetail say, it looks like there's no way to replace the wire (I guess it's different than on cars...), so it sounds like this is the part to replace...

Thanks for the info -- I'll post back with my results once I get the part.

They sell a rubber boot and squeeze-on end that you can replace the "terminal end" that connects to the plug itself...

Got the part and popped it in.  One pull and the darn thing fired right up!!

Now I need to tune it up, as I'm having trouble getting the right mix and it's hard to start...

Thanks for the advice!
