Fuel/air mixture ratio is richness. Too much air & too little fuel gives a
lean mixture, causing overheating, burned valves etc. Too little air and
too much fuel and you get incomplete burning, fouled plugs/pistons/rings
etc, smoke, excessive consumption...and that hidden danger,
cylinder-wall-wash, which is unburned fuel getting past the rings and
thinning the oil on the bores, causing very rapid wear (a real problems
with diesels in particular).
