318 Running Rough / Backfiring
Pulled plugs. My goodness they are black haha. Only about 1200 miles on the rebuilt engine and these plugs. Guess it's running pretty rich.
Weird that they are uneven with the amount t of foiling though. The darkest are the plugs from the front of the engine (plugs from cylinders 1&2) and they get lighter towards the back (plugs from cylinders 7&8).
Thoughts on why the front plugs would be so much darker?
