        Rich: Depending on what you are using the motor to do. I run NOTHING but NGK B-6S, B7S, B8s. just different heat ranges for slow or fast running but rule of thumb, use B7S

          Interesting question. My best info says it came with Champion J3 @ .030″ An old Champion book says J62R @ .023″. I’ve never heard of either of those. Better ask Russ Larson, the Martin guru.
