Replacement Spark Plugs for Lawn Boy Power Tillers
The spark plug in your Lawn Boy gasoline-powered Tiller is vital to its performance. A Tiller, also known as rototiller or powered tiller, relies on the spark plug to properly fire for the engine to start. If the spark plug fails to fire properly, it might cause issues with the trimmer and, eventually, the Tiller will not start. You can remove the rototiller spark plug to inspect. Examine the spark plug for dirt, blackening, and grime. If a spark plug is no longer in good condition, it should be pretty obvious. Please see our Tiller Repair Help and Troubleshooting section for more information on replacing your Lawn Boy Tiller's spark plug. Our Tiller repair section contains step-by-step directions and videos for replacing the spark plug on your Lawn Boy rototiller.

When To Replace Your Lawn Boy Rototiller Spark Plug?
Lawn Boy rototiller fuel lines can get clogged, causing the engine to lose power. To avoid this issue, try changing your spark plug as part of routine rototiller maintenance. A good rule of thumb is to change the spark plugs in rototillers every 100 hours of use. It is advisable to replace the spark plug before the engine fails to start.
