Like in all other lawnmowers, your Briggs and Stratton engine may face diverse ignition issues in the long run or even for sitting idle for too long. But on the bright side, we present a whole guide to help you resolve all your problems with the Briggs and Stratton coil safely by yourself.
This guide contains the safest as well as easiest way to fix or replace your ignition components. But, before we start discussing the instructions, let’s have a look at the chart beneath that outlines common coil armature problems of our lawn mower engines and their possible solutions.
Briggs and Stratton Coil Problems
| Briggs and Stratton Coil Issues | Feasible Solutions |
| No spark at all | Test the coil & or spark plug (replace the faulty component) |
| Loose or Rusted connection and coil sparking after multiple try each time | Detach and clean armature module, then readjust it |
| The Motor makes hissing or knocking sounds | One of your coils is not functioning; replace it. |
How To Remove An Ignition Coil On Briggs And Stratton Engines
Replacing the coil armature is a relatively straightforward job. But fixing a heavy machine is never risk-free. So, before you start, we advise you to take precautions and keep a safe distance each time you start the engine. Because it rotates dangerously, generates heat, and can damage you severely on contact.
To replace your ignition module, the following tools will come in handy. So, keep them close before starting. You can also use suitable substitutes for them, whatever works. Just make it safe.
Before we start on the step-by-step instructions, consider going through the entire procedure once and start following on your end on the second read. This will narrow your chances of making mistakes even on the first go.
Let’s Begin:
How To Clean And Test The Briggs And Stratton Coil Assembly
The tools you will need at this step are:
First, after you pull out the coil, see if it has rust in its mouth and then clean it with sandpaper or files. Then clear out the debris using a dry cloth. Since cleaning it may solve old Briggs and Stratton no spark issues. Now, you are ready to test the ignition coil.
For inspecting the resistance, you need three parts of your ignition coil identified and labeled. They are:
- Coil Base.
- Kill Wire.
- Spark Plug cap.
In the service manual, you will find an Ignition coil winding resistance diagram that presents the resistance limit in between any two of the three parts we mentioned.
How To Reinstall A Coil On Briggs And Stratton Engines
To reinstall the coil or to plant a new coil on your lawnmower engine, the tools we mentioned in the removal guide will be adequate.
But before that, verify your replacement coil meets the specs for your engine. To double-sure, compare the replacement with the Briggs and Stratton OEM part. A replacement is a must when it shows Briggs and Stratton bad coil symptoms.
So, let’s begin reinstalling.
How To Replace A Spark Plug On Briggs And Stratton Engines
Although, the spark plugs are more resistant to wear and tear than the ignition module. So, we expect cleaning or replacing the coil will solve your problem.
However, if the fix is not sufficient or you are not satisfied with the spark after troubleshooting, you can also change the spark plug.
In this case, you need to get the right one for your engine. The best option is buying an OEM part. Yet, if you opt for an aftermarket spark plug, be sure it is compatible with your ignition module and engine. To verify if it meets such specifications, compare it with the Briggs & Stratton spark plug part number, and you should be good.
Changing the spark plug connected to the coil assembly will be a piece of cake for you considering you underwent the previous instructions, at least in your head.
Here it is:
So, we will be delighted if this guide saves you the trouble and time of looking for a technician.

Frequently Asked Questions (FAQs)
How do I know if my Briggs and Stratton coils are bad?
You have to inspect Briggs and Stratton ignition coil symptoms like no spark when you crank the engine, poor spark, poor rotation power, and weird sound for a twin-cylinder motor, etc. Moreover, according to our guide, you can test the ignition coil with a multimeter and rule it out as a bad one indisputably.
How do you test a coil on a Briggs & Stratton engine?
To test the coil, you need the wire windings diagram of your coil, a multimeter set to test resistance, and a proper labeling and testing sequence. To avail of these in one place, please follow our guide.
How many ohms should a Briggs & Stratton coil have?
Various Briggs and Stratton coils have various ohm requirements in between two of the three coil junctions (base, kill wire, and lead cap.) To know the ohm for your engine, stick to the service manual and test it with a multimeter to verify if they meet the engine specs.
How do you test a Briggs and Stratton coil with a multimeter?
To test your Briggs and Stratton coil with a multimeter, connect a combination of base, kill wire and spark plug cap with your first and second multimeter clip and set your multimeter to test resistance (in ohms), and rotate the indicator to 20kΩ. Test and see if it resides within the winding chart limit.
Bottom Line
None of our everyday equipment is above issues. But, if we ignore them, they can snowball and respond with bigger troubles.
