Rotary and U! What is flooding, and how can I avoid it?

Q. What is flooding, and how can I avoid it?
A. By design, the rotary engine uses both gasoline and oil. “Flooding” occurs when, as the owner’s manual states, there is “excessive fuel in the engine.” To avoid flooding, Mazda suggests a “short driving trip procedure” for trips that are too short to warm up the car adequately:

1. Start car
2. Move vehicle
3. Warm engine for 5 minutes at idle
4. Raise engine speed to 3000 RPM for 10 seconds
5. Return to idle
6. Turn off engine

To help further remove the excess fuel, it is recommended that you rev your engine to at least 3000 RPM before shutting it off.

In the event of a flood, the following start-up procedure should be performed:

1. While the accelerator pedal is fully depressed, turn the ignition switch to the START position and crank the engine for 7 to 8 seconds.

2. Release the ignition switch and accelerator pedal.

3. Start the engine as normally without depressing the accelerator.

I flooded my 7 one time and all I did was crank till she fired...

one good way to not flood the engine... dont give it any gas untill the car "starts"

also make sure to bring yrou car up to redline atleast once on every trip you make.. (this helps to burn off cabron so u dont carbon lock)

Thanks. Yeah got that fixed. I had maybe 2 rx7 flood out of 15+ I owned, and both times where my fault. As long as you take care of them they will take care of your zoooom needs.
