I know its come on here before but I can't find the listing. What Champ plugs are we using in the 1978 6hp long shaft. Gaping would also be nice. : )

That is what the local shop said but how come the sticker on the motor says Champion 7L8V? Was that plug discontinued?

Don't known, but the above is BRP's 2007 recommendation. BTW, that's L78V, isn't it? If so, it's still available.
