Any ideas?


Rust color is pretty close if you're running racing gas.......probably still alitlle rich. Racing gas should produce a tan colored electrode when the mixture is correct. I would think from what you're saying that you're getting a dark tan, or rust, which is alittle rich.......

Have seen some octane boosters put a fuzzy orange/rust color crap on plugs
