proper s/plugs for 1966 33 hp Johnson

[kfa4303]

Hello all. Just wanted to know if anyone knows the correct modern s/plugs for a 1966 33hp Johnson (RXEL-14D). The manual says J4J, however it currently has Champion J6C plugs, which have worked in the past.

J4C Champions Gap .030...if you run at slow speeds alot...trolling...gap at .035...less carbon fowling with the larger gap

You should be able to use J6C's in that mtr with no probs at all gapped at .030".

Use the J4Cs for normal use, J6Cs for extensive trolling. .030 for either.
