A mixture of normal richness is easily fired. The gap for a Pratt and Whitney Double Wasp is /was just .012". Large gaps assist idle when mixture can be dubious, assuming the sytem can muster and stand high volts. (gaps for magnetos are small to reduce stress).
Most Seven owners seek every mousepower extractable and sunken valves also a consideration, so unlikely anyone is running weak mixes as moderns do so little case for wide gaps.
