G'day twr7cx, are you related to C3PO and R2D2...?
Also clean the points and the slip ring/carbon pickup brushes.
Rough Spark plug equivalent of 'recommended' Champion N3 in NGK is roughly B7ES,BP7ES or B8ES,BP8ES (more rellies?),which ever works best.
I tried BP6ES as a bit hotter, worked fine but changed jets and went back to the 7's for now. The 'P' just means 'protruding electrode'.
There's a spark plug cross reference table I found with a search, but I can't locate it since my hard-drive died last week after I bashed the macbook in the wrong place
Don't want to give false hope, but that may help....?
Cheers,duTch
