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.
