Briggs and Stratton Timing Problems Unraveled: Expert Solutions Revealed!


Picture this: It’s a beautiful sunny day, and you’re ready to tackle a long to-do list. But as you start up your trusty Briggs and Stratton mower, it sputters and coughs, refusing to cooperate. Frustrated, you realize something is off – the timing of your engine.
Welcome to the world of Briggs and Stratton timing problems, where the performance of your lawn care equipment hinges on precise timing. In this article, we’ll take you on a journey through the ins and outs of Briggs and Stratton timing issues, guiding you every step of the way.

Understanding Briggs and Stratton Timing

Before we dive into the nitty-gritty, let’s have a quick primer on how Briggs and Stratton engines work. These powerhouses rely on a complex interplay of moving parts, with timing being their secret sauce.
Timing determines when precisely the spark plug fires, ensuring the right mix of fuel and air explodes at the exact moment for optimal performance. Just like a fine-tuned orchestra, if the timing is off, chaos ensues, ruining the sweet symphony of your mower’s engine.
And trust us, you’ll know when timing goes haywire! Your Briggs and Stratton engine might exhibit symptoms like misfires, backfiring, decreased power, or even refusing to start altogether. These warning signs are your engine’s way of crying out for help.

Diagnosing Briggs and Stratton Timing Problems

Now that we know why timing is crucial, let’s roll up our sleeves and diagnose those pesky timing issues. Luckily, you don’t need a degree in rocket science. With a few simple steps, you can pinpoint the problem hiding within your Briggs and Stratton engine.
Step 1: Checking the Flywheel Key
The flywheel key is a small but mighty part that plays a vital role in engine timing. Over time, it can shear, throwing your timing out of whack. By carefully inspecting and replacing a damaged flywheel key, you can get the timing back on track.
Step 2: Inspecting the Camshaft and Crankshaft Alignment
Remember that intricate dance of moving parts we mentioned earlier? Well, the camshaft and crankshaft need to be in perfect alignment for your engine’s timing to be spot on. A thorough inspection and adjustment of these components can solve many timing headaches.
Step 3: Testing the Ignition Coil
No, we’re not talking about a spellbinding circus act here. The ignition coil is responsible for generating the spark that ignites the fuel and air mixture. If it’s faulty, your engine’s timing will suffer. Testing and replacing the ignition coil if necessary will bring back the spark in your mower’s life.
During diagnosis, keep your eyes peeled for telltale signs like damaged flywheel keys, misaligned camshafts or crankshafts, or worn-out ignition coils. These little clues will lead you to the timing gremlins wreaking havoc on your engine.
Remember, don’t be afraid to explore alternatives if you’re not comfortable with the diagnosis process. Diagnostic tools or the expertise of a professional can save you time and headaches.
Stay tuned for the next part of our adventure, where we’ll share the secrets to fixing Briggs and Stratton timing problems, ensuring your equipment runs like a dream.
As a seasoned lawn care technician, I’ve encountered my fair share of engine troubles. One problem that has left me scratching my head and reaching for the toolbox is Briggs and Stratton timing issues. Let me tell you, folks, getting the timing just right in these engines is crucial for peak performance. So, today, I’m here to give you the lowdown on understanding Briggs and Stratton timing problems and how to tackle them like a pro.

Why Timing Matters

Imagine this: you’re out mowing a lawn, engine roaring, and suddenly, your Briggs and Stratton-powered mower starts sputtering and losing power. Frustrating, isn’t it? Well, my friend, this could be due to a timing problem. You see, timing refers to the precise coordination between the engine’s internal components, ensuring they work together harmoniously. When the timing is off, it’s like a symphony gone wrong – the result is a cacophony of misfires, backfires, and limited power.

Fixing Briggs and Stratton Timing Problems

Have you ever dealt with a stubborn Briggs and Stratton engine that just won’t start? As a seasoned lawn care technician, I’ve encountered my fair share of frustrating moments with these engines. One common culprit behind such troubles is timing problems. But fear not, my fellow green thumbs! In this article, I’ll guide you through the process of fixing Briggs and Stratton timing problems, sharing my own experiences and insights along the way.

The Importance of Timing in Briggs and Stratton Engines

Briggs and Stratton engines are reliable workhorses, but even they can suffer from timing issues. Timing is everything when it comes to engine performance. Just like a finely choreographed dance, the precise coordination between various internal components is essential for smooth operation. When timing goes awry, your engine may refuse to start, sputter, or run erratically.

Diagnosing the Culprit

Our analysis of this product revealed that diagnosing timing problems is the first step towards fixing them. Fortunately, you don’t need a degree in rocket science to do so. You just need a keen eye and a few handy tools.

Step 1: Checking the Flywheel Key

Sometimes, a sheared flywheel key can throw off your engine’s timing. This tiny component connects the flywheel to the crankshaft and plays a crucial role in maintaining synchronization. So, if you suspect timing issues, start by inspecting the condition of the flywheel key. A visual examination will quickly reveal if it’s damaged or sheared.

Step 2: Inspecting Camshaft and Crankshaft Alignment

Another common cause of timing problems lies in the alignment of the camshaft and crankshaft. Over time, vibrations or improper installation can knock these crucial components off balance. To check for misalignment, remove the engine cover and visually inspect the camshaft and crankshaft. They should be properly aligned, with corresponding marks facing each other.

Step 3: Testing the Ignition Coil

If the flywheel key and alignment seem fine, it’s time to turn our attention to the ignition coil. A faulty ignition coil can cause irregular sparks and disrupt engine timing. To test it, you’ll need an ohmmeter. Measure the resistance between the ignition coil’s terminals and consult your engine’s manual for the correct values. If the readings are outside the specified range, it’s time to replace the ignition coil.

Fixing the Timing Woes

Based on our observations, fixing Briggs and Stratton timing problems can be a DIY project if you’re comfortable with basic engine repairs. Remember, safety comes first, so ensure the engine is switched off and cooled down before you begin any repairs.

Step 1: Replacing a Sheared Flywheel Key

If the culprit is a sheared flywheel key, fear not. Replacing it is relatively straightforward. Remove the flywheel and old key, clean the mating surfaces, and install a new key. Make sure it snugly fits into the keyway before reassembling everything.

Step 2: Adjusting Camshaft and Crankshaft Alignment

To correct misaligned camshaft and crankshaft, loosen the bolts holding them in place. Gently rotate the camshaft until its timing mark lines up with the crankshaft’s timing mark. Once aligned, tighten the bolts securely. A little finesse can go a long way here to ensure perfect timing.

Step 3: Troubleshooting and Replacing Faulty Ignition Coils

If your timing problems stem from a faulty ignition coil, it’s time for a replacement. Remove the old coil, carefully disconnecting the wires. Install the new coil in its place, reconnect the wires, and secure it firmly. Remember to consult your engine’s manual for any specific instructions.

Preventing Future Timing Nightmares

Don’t let history repeat itself! Once you’ve fixed your Briggs and Stratton engine’s timing, take preventive measures to keep it in top shape.
Regularly cleaning and inspecting the flywheel key is crucial. Remove any debris or dirt that may affect its performance. Invest time in routine maintenance by checking and adjusting camshaft and crankshaft alignment. Small tweaks can save you from major headaches down the road. And finally, replace the ignition coil at recommended intervals to prevent timing problems from sneaking up on you.


As a lawn care technician who has navigated the tangles of Briggs and Stratton timing problems, I hope this guide has shed light on this common issue. Remember, timing problems may seem overwhelming at first, but with a little perseverance, you can diagnose and fix them like a pro. So, gear up, get your hands dirty, and revive that engine to bring life back into your lawn. Happy mowing!
