Stock 78 400 motor, Seems to run good drive good but what's up with these plugs? They all look wet and dark like this. I've never been good at tuning carbs (running an eddy 1406), is this a rich condition? Need a hotter plug maybe? I really don't think it's oil as it's a low mile motor and it doesn't blow smoke at all. Appreciate any help !
