 I pulled my plugs and took a look at them.  They are Champion N 9 and appear
 to be a light brown on the tips.  Haynes says N 5 was the factory issue and
 I have read here that N9YCC is a standard replacement.  Is this right?

Light brown is ok.  The numbering system for Champion plugs like a lot of 
other things changes over the years.  The numbers themselves change less so 
and the difference between N9 and N9YCC will be a copper core (CC) and I 
forget what the Y means (Have used NGK plugs for years).  
Why are you changing them.
I think hunting means a rising and falling engine tone - hold the choke out 
for a long time when the engine is warm and you will get the general idea.
A cheap tacho is a cheap tacho.
