Hi,

You're most probably right, but using a Hi-Temp AS w/ high metal content (usually Copper) can effectivelty increase the surface area of the Ground or Common terminal with the Head by making contact (via a brige through the AS) to the back side of the threads. Would this interfere? I don't know, but I am just postulating a possible cause to the Lister's observations. This is why I said that it could (possibly) interfere.

An Insulator (regular AS) probably would interfere with such a function. The Spark would still be OK due to the high voltage involved which would readily overcome any added resistance...

Happy Motoring!... Jim'99
