I couldn't get a response from the archives, so...

I'm a bumbling, certified NON-mechanic.

I own an '88 Westy.  The manager of my apartment building was a mechanic in
Germany for many years.  He tells me that one of my spark plugs is not
firing - he bases this on the sound of the engine.  I tend to agree with him
due to a recent dip in hill-climbing power.

He doesn't have the time to change the plugs for me, and (don't laugh) I've
never done it.  I can borrow a spark plug wrench from a friend; can anyone
with some spare time give me a walk-through of how exactly to change the
plugs, i.e., tools needed, "Whatever you do, DON'T disconnect the Widget"
etc.?

Also, any recommendations of spark plug brands or types favored by Westy
owners would be appreciated.  Do double- and triple-fire spark plugs make
any difference?

Thanks for any help.
