Small Engines Repair: Tune-Ups And Repairs

Small engines, like those found in lawnmowers, leaf blowers, and chainsaws, are essential tools for many homeowners and professionals. Although reliable, small engines require regular maintenance and repair to keep them running smoothly.

Here are some basic steps to take when repairing or tuning up small engines.

Tools and Safety Equipment

Small engine repair can be less intimidating than working with bigger, more complex engines. If you're attempting to repair or tune up your small engine, you will need to have the right tools and safety equipment.

  • Tools: before you begin any repair or maintenance work, it's important to have the right tools and supplies on hand. This may include a spark plug wrench, a socket set, a torque wrench, a compression tester, and various cleaning materials. You may also need to purchase replacement parts, such as spark plugs, air filters, and oil filters. It's important to gather your tools and supplies before you start the job. If you don't have the tool or part you need, you might need to leave the project half-done.
  • Safety First: it's critical to wear protective gear, such as safety glasses and gloves, when working on small engines. Make sure the engine is turned off and the spark plug is removed before beginning any repair work. This will prevent the engine from engaging while you work on it.


A routine small engine tune-up typically involves replacing the spark plug, cleaning, or replacing the air filter, and changing the oil. These simple maintenance tasks can help keep your engine running smoothly and extend its life.


The source of most small engine repairs can be spotted with a few basic diagnostic checks.

  • Compression: if your engine is not starting or is running poorly, it may be due to low compression. Use a compression tester to check the pressure in the cylinders. If the pressure is low, it may be due to a worn or damaged piston or cylinder.
  • Damaged Parts: if you find any damaged parts, such as a worn or broken spark plug, you'll need to replace them. In some cases, you may be able to repair the part, such as by replacing the spark plug electrode or cleaning the carburetor. A quick visual inspection can help find these parts.

Small engine repairs and tune-ups require a basic understanding of the engine and the right tools and supplies. By following these steps and taking the necessary precautions, you can keep your small engine running smoothly and extend its life.
