2011年9月21日 · They have piles of Champion CJ6, RCJ6, & RCJ6Y, and some Arnold brand equivalent spark plugs marked way, way down in their lawn and garden clearance section. I generally use tried and true Champion J6C spark plugs in my menagerie of old OMCs as has been recommended countless times, but the cheapskate in me is intrigued.
