Is a carburetor too rich or too lean when it bogs down when you open the throttle?

Usually, when opening the throttle, if the engine bogs down the problem is usually a too lean situation. Often it is a clogged fuel jet, fuel filter, etc and the rapid increase in air entering the cylinder is not associated with the appropriate increase in fuel. The engine is being starved of fuel and too much air is causing poor combustion. It would be unusual for it to be a too rich situation since rarely is air flow reduced when the throttle is opened, unless the air filter is totally clogged, which although possible is unlikely.
