Welcome to our blog, where we will be discussing the Briggs and Stratton Magnetron, a revolutionary ignition system that has been making waves in the small engine industry. In this article, we will explore the features and benefits of the Magnetron, as well as provide some tips and troubleshooting advice for those who own or are considering purchasing a Briggs and Stratton engine equipped with this technology.

What is the Briggs and Stratton Magnetron?

The Briggs and Stratton Magnetron is an advanced ignition system that replaces traditional ignition points and condensers found in older small engines. It utilizes a magnet and coil to generate a high-voltage spark, resulting in reliable and efficient engine starting.

How does it work?

The Magnetron system consists of a permanent magnet embedded in the flywheel, which rotates past a coil of wire mounted on the engine block. As the magnet passes by the coil, it induces a voltage in the wire, creating a spark at the spark plug. This eliminates the need for mechanical points and condensers, reducing maintenance and improving overall engine performance.

Advantages of the Magnetron

There are several advantages to using the Briggs and Stratton Magnetron:

  • Improved reliability: The Magnetron system eliminates the wear and tear associated with ignition points, resulting in a more reliable ignition system.
  • Easy starting: The high-voltage spark generated by the Magnetron ensures quick and easy engine starting, even in cold weather.
  • Reduced maintenance: With no points or condensers to adjust or replace, the Magnetron system significantly reduces maintenance requirements.
  • Consistent performance: The Magnetron delivers consistent ignition timing, resulting in smooth engine operation and optimal fuel efficiency.

Tips for Maintaining and Troubleshooting the Magnetron

Regular maintenance

To ensure the longevity and optimal performance of your Briggs and Stratton Magnetron system, it is important to perform regular maintenance:

  • Clean the flywheel magnet: Over time, the flywheel magnet can accumulate dirt and debris, which can interfere with the magnetic field and reduce spark output. Regularly clean the magnet using a soft brush to remove any buildup.
  • Inspect the coil: Check the coil for any signs of damage, such as cracks or corrosion. If any issues are found, replace the coil to maintain proper ignition system function.
  • Check spark plug condition: A worn or fouled spark plug can hinder ignition performance. Inspect the spark plug regularly and replace it if necessary.
  • Ensure proper air gap: The air gap between the flywheel magnet and the ignition coil is critical for proper spark generation. Consult the engine's manual for the recommended air gap measurement and adjust if needed.

Troubleshooting common issues

If you encounter any issues with the Magnetron system, here are some common problems and possible solutions:

  • No spark: If there is no spark at the spark plug, check the flywheel magnet and ignition coil for damage. Also, ensure that the air gap between the magnet and coil is within the recommended range.
  • Weak spark: If the spark appears weak or inconsistent, verify that the spark plug is in good condition. Additionally, check the flywheel magnet and coil for any signs of wear or damage.
  • Intermittent spark: An intermittent spark could be caused by a loose or faulty connection. Inspect all electrical connections, including the spark plug wire and ignition coil wire, and ensure they are secure.
  • Engine misfires: If the engine is misfiring, it could be due to a faulty spark plug or a problem with the fuel system. Check the spark plug and clean or replace it if necessary. Additionally, inspect the fuel lines and fuel filter for any blockages.


The Briggs and Stratton Magnetron is a game-changer in the small engine industry, offering improved reliability, easy starting, reduced maintenance, and consistent performance. By following the tips for maintenance and troubleshooting provided in this article, you can ensure that your Magnetron system continues to operate at its best. Whether you are a small engine enthusiast or a professional, the Magnetron is a technology worth considering for your next engine purchase.
