lean & rich

[Jensen, Mike]

This may sound like a very silly question, but when it is said that an
engine is running lean it means that it is getting excess air for the
amount of fuel that it is getting , and vice versa for a rich burning
engine (excess fuel for the amount of air that it is getting)
