Interesting observation Bernd.
If there was spark leakage though the core of the spark plug
all the way to the heat shield then that would mean the
ceramic insulator was either defective or slightly cracked
near the base of the spark plug.
Given the fact that Hercules put the plugs in at the factory using
a 20ft long torque bar that just may be possible. Too bad I tossed
my stock plugs, would like to inspect them. However I do remember
breaking every single one of those crappy things taking'em out.
However, I seem to recall a bunch of pinger's out there replacing
plugs to no avail. ????
The mystery continues...

Subject: DML: Pinging and Pondering
Well, I was pondering around with the Pinging Problem (as well as
figuring
out a way to fill up my beer glass without having to get up) and took a
close look at the (now removed) plug heat shield. There are traces of
arcing on the inside bottom, nearest to the hex-part of the
plug. Hmmmm....Is this from the factory plugs (nasty little buggers),
a
problem that i've missed, a probable cause to the pinging...???
Ideas anyone?
