and i get a sparking sound when engine is running, and you can see a small spark at the top of the plug, only 4 of the new plugs do this, i was hoping some one could shed some light on this, than you, bob
 
Ive had good luck with champ D-21's for going on 20 yrs. Maybe you have old or cheap wires that are leaking to ground. ken ct. Also in a 36
 
If you have carbon radio resistor type wires this happens when they get old and break down. Start your engine in the dark and see if you can see sparking along the plug and coil wires.
