How is a flooded engine cleared?
The conventional remedy for a flooded carbureted engine is to steadily hold the throttle full open (full power position) while continuing to crank the engine. This permits the maximum flow of air through the engine, flushing the overly rich fuel mixture out of the exhaust.
Can you fix a flooded engine?
On the other hand, flooded engines are the result of an imbalance between air and fuel in the engine system. You can fix a flooded engine. Conversely, floods can be very destructive, and the damaged to the engine can be quite extensive. Therefore, a flood-damaged engine might need an expert.
What happens when an engine is flooded?
If that sounds familiar, then probably your engine was flooded. This happens when there’s too much gas and not enough oxygen in the engine, causing the spark plugs to get wet and making it difficult to ignite the fuel. This is one of the most common problems for carbureted cars.
How do you tell if an engine is flooded?
You can tell if your engine’s flooded when you spot these signs:
- Very fast cranking (the engine sounds different when you turn the key – usually a ‘whirring’ sound)
- A strong smell of petrol, especially around the exhaust.
- The car doesn’t start, or starts briefly and cuts out again.
How long does it take for a flooded engine to clear?
Perhaps the best remedy for a flooded engine is time. Simply open the hood of your car and let excessive fuel evaporate for as long as you can. After about 20 minutes try starting your car again without hitting the gas pedal. If this still does not work, you may have to check your spark plugs.
What do I do if I over Prime my engine?
But, if you’ve over-primed a lot, with fuel dripping from the exhaust, don’t try to start the engine. Instead, make sure the engine is off, and open the throttle to full. This will open the engine’s butterfly-valve, sending air throughout the engine, evaporating the excess fuel.
