I'll add 2-3% more fuel to cyl6 and recheck the plug again afterwards. As for Cyl4, I also believe it's oil unfortunately. Valve seals are new and motor doesn't smoke on startup or ever really so I'm presuming it's ring related and only smokes slightly at WOT. I'm currently speaking to my engine builder and at his request, just sent the same spark plug photos, my target AFR tables and a few logs. We'll see what he says tomorrow. Engine still runs great, so I'm not overly concerned. At worst, I'll pull the block this winter and get rings checked and cylinders rehoned. Thanks again! -
Yes, well, then the possibly lean(er) look of #6 makes sense. #4 looks oil wet, not rich.
