Introduction To Magneto Issues
Understanding magneto issues in Briggs & Stratton engines is crucial. A magneto generates the spark needed for combustion. Without it, the engine won’t start. Identifying and fixing magneto problems can save time and money.
Common Symptoms
Several symptoms indicate magneto issues. These signs include weak or no spark. The engine may also misfire or run poorly. If the engine won’t start, the magneto could be the culprit.
Importance Of Timely Fixes
Fixing magneto problems quickly is essential. Delayed repairs can lead to more damage. This can result in costly repairs or replacements. Addressing issues early can prevent further engine damage.
Tools Needed For Troubleshooting
Troubleshooting a Briggs & Stratton magneto can be a straightforward task. Having the right tools is essential. The correct tools can make the process easier and more efficient. This section will cover the tools you need for successful troubleshooting.
Essential Tools
To troubleshoot a Briggs & Stratton magneto, you will need basic tools. A spark tester is a must-have. This tool helps you check the spark plug’s function. Another key tool is a multimeter. It measures voltage, current, and resistance. You will also need a screwdriver set. Different sizes ensure you can handle various screws. Lastly, keep a wrench set handy. It helps you remove and tighten bolts easily.
Optional Tools
While not essential, some tools can make the job easier. A feeler gauge measures the gap between the magneto and flywheel. This tool ensures accurate measurements. A torque wrench is also useful. It helps you apply the correct amount of force when tightening bolts. Finally, an ignition coil tester can be beneficial. This tool checks the coil’s condition, saving time in diagnosing issues.
Safety Precautions
When troubleshooting the Briggs & Stratton magneto, safety should be your top priority. Following proper safety measures can prevent accidents and injuries. Below, we’ll cover essential personal and equipment safety tips.
Personal Safety Tips
- Always wear protective gear. Safety glasses, gloves, and closed-toe shoes are a must.
- Disconnect the spark plug. This prevents accidental engine start-up.
- Work in a well-ventilated area. Avoid inhaling fumes from the engine.
- Keep a first-aid kit handy. It’s better to be prepared for minor injuries.
Equipment Safety
- Ensure the engine is cool. Hot engines can cause burns.
- Use the right tools. Incorrect tools can damage the magneto or engine.
- Check for fuel leaks. Fuel leaks can be hazardous when working on the engine.
- Follow the manual. Always refer to the manufacturer’s instructions for troubleshooting steps.
Diagnosing Magneto Problems
Experiencing issues with your Briggs & Stratton magneto? Diagnosing these problems can be straightforward. By performing a few checks, you can identify the problem and find a solution. Follow these steps to troubleshoot your magneto effectively.
Visual Inspection
Start with a visual inspection of the magneto. Look for obvious signs of wear or damage. Check for loose connections, corroded terminals, and any visible cracks or breaks.
- Inspect the magneto’s housing for cracks.
- Check for any burnt or discolored areas.
- Examine the wiring for wear or fraying.
These visual clues can help you identify if the magneto needs repair or replacement.
Using A Multimeter
If the visual inspection reveals no issues, use a multimeter to test the magneto. This device measures electrical resistance and can tell if the magneto is functioning properly.
- Set the multimeter to the resistance (ohms) setting.
- Connect the multimeter’s probes to the magneto’s terminals.
- Read the resistance value on the multimeter’s display.
Compare the reading to the manufacturer’s specifications. If the value falls outside the recommended range, the magneto may be faulty.
A table can help you understand the multimeter readings:
| Resistance Reading (Ohms) | Status |
|---|---|
| 0 – 0.5 | Short circuit |
| 0.5 – 10 | Operational |
| 10 – Infinite | Open circuit |
Testing with a multimeter ensures that you accurately diagnose the magneto’s condition. By following these steps, you can determine if the magneto needs repair or replacement.
Fixing Common Magneto Issues
Briggs & Stratton magneto problems can cause your engine to misfire. Understanding and fixing common issues can save you time and money. Here, we will discuss two primary fixes: replacing the spark plug and cleaning the ignition coil.
Replacing Spark Plug
A faulty spark plug often causes engine problems. Start by locating the spark plug on your engine. Remove the spark plug wire carefully. Use a spark plug wrench to unscrew the old spark plug. Check for signs of wear or damage. If the spark plug is dirty or cracked, replace it with a new one. Ensure the new spark plug matches your engine specifications. Screw in the new spark plug by hand, then tighten with the wrench. Reconnect the spark plug wire securely. This simple replacement can solve many magneto issues.
Cleaning Ignition Coil
A dirty ignition coil can prevent proper engine function. First, locate the ignition coil on your engine. Disconnect the wires attached to the coil. Remove the ignition coil using a screwdriver. Clean the coil with a soft brush or cloth. Remove any dirt or debris. Inspect the coil for cracks or damage. If the coil is damaged, replace it. Reinstall the cleaned coil and reconnect the wires. Cleaning the ignition coil can restore proper engine performance.

Advanced Troubleshooting Techniques
Advanced troubleshooting techniques can help you diagnose and fix complex issues with your Briggs & Stratton magneto. Sometimes, basic troubleshooting steps are not enough. This is where advanced techniques come in handy. These methods require a bit more technical know-how, but they can save you time and effort.
Testing Flywheel Magnet
The flywheel magnet plays a crucial role in generating the necessary spark. To test the flywheel magnet, follow these steps:
- Remove the flywheel cover carefully.
- Locate the magnet on the flywheel.
- Use a screwdriver to check the magnet’s strength. The screwdriver should be attracted firmly.
- If the magnet is weak, it needs replacement.
Checking Wiring Connections
Wiring connections are vital for the magneto’s proper operation. Loose or damaged wires can lead to failure. Here’s how to check the wiring connections:
- Inspect all wires connected to the magneto.
- Look for signs of wear or damage.
- Ensure all connections are tight and secure.
