Today you are going to read complete our How To Replace A Starter On A Briggs And Stratton Engine. Have you ever been excited to start mowing but your riding mower refuses to start? You have already turned the key and heard a click, but the problem is, it does want to start!
If you are in this scenario, don’t freak out. A defective starter component of your riding mower might be the reason for the failure. There are several signs of defective starter such as a clicking sound especially when you press the ignition button, a cranking loud sound and also, the failure to start the engine.
Typically, it begins with difficulties before completely failing to start. The majority of us make the error of continually attempting to switch on the ignition which will just worsen the situation as it can cause another problem.
How Does The Starter Work?
The starter is the component that ignites your engine’s internal combustion. It consists of a starter motor which placed the solenoid inside it. Electric current is sent to the starter motor when the battery is powered up due to ignition. The engine starts to fire up after the starter rotor moves which is caused by the starter relay (on).
In simple words, that’s how the starter works. If your riding mower does not want to start, it means the starter is not able to initiate ignition to fire up the engine. So, what you can do is, replace the starter.

2. To gain access to everything, unplug the headlight wiring harness before lifting the hood or engine cover. Detach it, and take off the hood or engine cover. Set them aside for now.
3. Pull off the air filter cover by rotating the retaining knobs counterclockwise. Then, take out the air filter. Unplug the screw inside the filter housing with a ¼ inch nut driver.
4. Remove the four mounting bolts from the blower housing by using a ⅜ inch socket or wrench, and then remove the blower housing. After that, remove the oil drain tube too.
5. Then, using a 7/16 wrench, unscrew the bolts that secure the wire to the starter and remove the wire.
6. Use a ½ inch socket and wrench to unscrew the starting mounting bolts. In total, the starter is secure by using two bolts only which is need to be removed.
7. And now you may take out the old starter to replace it.
8. To install the new starter, first, align it with the engine and then fasten it in place using the mounting bolts.
Pro Tip: Before tightening the bolt, make sure the wire retainer is in place (under the left bolt) and the wires are secured.
9. Connect the wire to the starter and reinstall the nut to secure it.
In the next steps, you just need to undo all the previous steps done before.
10. Put back the blower housing as before and make sure it is placed on the air diverter properly. Secure it using the mounting bolts. The longer bolts are placed in the rear.
11. You also may need a new screw for the filter housing. Replace it and place the air filter to its place back. To secure, adjust the cover and turn the retaining knobs in a clockwise direction.
12. Connect the oil drain tube to the blower housing as before.
13. Lastly, install back the hood or engine cover. Do not forget to reconnect the headlight wire as before too.
