Introduction
When it comes to small engines, Briggs and Stratton is a well-known name in the industry. One crucial aspect of maintaining a Briggs and Stratton engine is ensuring the proper air gap for the armature. The armature air gap plays a vital role in the engine’s performance and overall functionality. In this article, we will explore the importance of the Briggs and Stratton armature air gap and provide tips on how to adjust it correctly.
Understanding the Armature Air Gap
The armature air gap refers to the distance between the ignition coil’s laminations and the magnets on the flywheel. This gap is essential for generating the necessary magnetic field to induce the spark in the spark plug. If the air gap is too wide or too narrow, it can significantly impact the engine’s ignition system, leading to poor performance or even engine failure.
Importance of Correct Air Gap
Having the correct air gap is crucial for the engine’s ignition system to function optimally. If the gap is too wide, the magnetic field might not be strong enough to generate a spark. On the other hand, if the gap is too narrow, the flywheel and armature might rub against each other, causing excessive wear and potential damage. Therefore, maintaining the proper air gap is essential for a reliable and efficient engine.
How to Adjust the Armature Air Gap
Adjusting the armature air gap requires some basic tools and careful attention to detail. Here’s a step-by-step guide to help you through the process:
Step 1: Safety First
Before starting any maintenance or adjustment work, make sure the engine is turned off and the spark plug wire is disconnected to prevent accidental starts.
Step 2: Removing the Shroud
Most Briggs and Stratton engines have a shroud covering the flywheel and ignition system. Remove the shroud carefully by unscrewing the bolts or clips holding it in place.
Step 3: Locating the Armature
Once the shroud is removed, locate the armature and flywheel. The armature is usually positioned near the top of the engine and connected to the spark plug wire.
Step 4: Measuring the Air Gap
Using a feeler gauge, measure the air gap between the armature laminations and the flywheel magnets. Refer to the engine’s manual for the recommended air gap specification.
Step 5: Adjusting the Air Gap
If the air gap is too wide, carefully bend the armature slightly closer to the flywheel. If the gap is too narrow, gently pry the armature away from the flywheel using a flathead screwdriver. Make small adjustments and recheck the gap until it falls within the recommended range.
Step 6: Reassembling the Shroud
Once the air gap is adjusted correctly, reassemble the shroud by securing it with the bolts or clips. Ensure that all connections are tight and secure.
Conclusion
Properly adjusting the Briggs and Stratton armature air gap is essential for maintaining a reliable and efficient engine. By following the steps outlined in this article, you can ensure that your engine’s ignition system functions optimally, leading to improved performance and longevity. Remember to consult your engine’s manual for specific instructions and recommended air gap specifications.
