Bill, The HR9 is a pretty hot plug's for the oil burners, but that temp
should keep them pretty clean . HR7or 8 would be good for the short hops
and
6's for the long haul driving. I like 8's for the stop and go traffic and
short hwy.

Subject: [DMCForum] Re: More tuning
Jeg's describes Accel Superstock @ 45,000 volts. You'll notice biggest
difference this winter.
Didn't realize until recently that 20% of combustion chamber temp is
absorbed by spark plug insulator. That's why I'm leery of the Bosch
HR9's currently in my block (purchased under advice of parts house
"technician"). Will try them to Fall Foliage but am taking some good
old Delco R44's just in case.
I think rule of thumb is: if plug isn't fouling, keep it cool.
What did you do about cap/rotor/wires?
