when doing this modification don't you have to put two plugs in BOTH holes? Mazda quotes the
ignition function as lose trailing plug lose 25% power, lose LEADING plug lose 75% power. This
would be per rotor of course. Not using both ignition positions will cause a loss of power
reguardless of the type of ignition used. Please enlighten me if I am missing something here.
Otherwise the post sounds a little bs. Bill Jepson

I don't understand what you man by:
"put two plugs in BOTH holes"

One of the reasons it is down on power with just the trailing
plug is the hole is so small the spark from that plug fails
to ignite the mixture from time to time.

I think this is a reasonable thing to do. Dennis Hayes is
quite honest and forthcoming IMHO. Why would he lie about something 
like this anyway.
