Well if it's rich to the point where it won't run (flooded)... the plugs will be extremely wet. Go pull a plug. What's it look/smell like? Repeated attempts at starting can keep the engine flooded for a while (at least it did on *my* car). If you can see/smell gas on the plugs, it's too rich. Spark plugs are cheap.

The Bentley describes how to check/set the mixture with the engine off. Basically you want to remove a fuel line from the fuel distributor and direct the resulting fuel into some sort of safe container.

Turn the fuel pumps on (they recommend a toggle switch between the #30 and #87 terminals on the fuel pump relay) but don't start the car.

They assume that mixture has been leaned out enough to eliminate fuel flow.. but you want to adjust it to the point that fuel begins to flow, and then back off by a half turn.

If you've already got fuel flow, I suppose you could lean the mixture out to the point of no fuel flow and start from there (no personal experience here). CW == more fuel, CCW == less fuel.
