Can you clean a fouled out spark plug?
How To Clean Fouled Spark Plugs. To safely clean a spark plug, you should use a wire brush or spray-on plug cleaner specifically designed for this ignition part. You can also use a sturdy knife to scrape off tough deposits.
What is the proper technique for clearing fouled spark plugs?
Try clearing the plugs by running your engine up to 2000 RPM on both mags leaning to about 50 RPM lean of peak (continue to lean until you maximize RPM, then lean further until you lose about 50 RPM).
How long should you let your engine cool before changing spark plugs?
Even after other parts of your engine have cooled down, the spark plugs may still be too warm to touch. Let your engine cool down for a couple of hours before you begin.
What should I use to clean a fouled spark plug?

What does it mean when a spark plug is fouled?
Carbon fouling is one of the potential fouling problems that happens to spark plugs. According to NGK Spark Plugs, when the insulator nose of the spark plug is coated, it is considered fouled. The website continues to explain that while carbon fouling can cause problems, if the spark plugs are cleaned,…
Can a coolant leak foul the spark plug?
Modern coolants do not cause this type of buildup quickly due to the reduction of phosphate, zinc and other additives that can contaminate the catalytic converters. Unfortunately, it also means that drivers will run a vehicle with a coolant leak for several thousand miles while the plug becomes slowly fouled.
Can a faulty spark plug cause an engine to stop?
Faulty spark plugs will cause issues with the performance of the engine that is easily noticeable. Below are some of the common warning signs that indicate faulty spark plugs in a car. An engine misfire results in the engine to stop for a moment and then regain its normal operation.

When to use hotter or colder spark plugs?
Use a colder heat range for leaner air/fuel mixtures. Rich air/fuel mixtures can cause the plug temperature to dip, allowing carbon deposits to build up on the tip. Use a hotter heat range for rich air/fuel mixtures. • Advanced ignition timing: In general, advanced ignition timing will raise the spark plug temperature.
Is it bad to clean your spark plugs?
The website continues to explain that while carbon fouling can cause problems, if the spark plugs are cleaned, there should not be any problems afterward unless the spark plugs were also damaged. Stop-and-go traffic, where a vehicle is stopping constantly, is never good for the vehicle.
What causes spark plug temperature to go up or down?
Rich air/fuel mixtures can cause the plug temperature to dip, allowing carbon deposits to build up on the tip. Use a hotter heat range for rich air/fuel mixtures. • Advanced ignition timing: In general, advanced ignition timing will raise the spark plug temperature.
