Common Reasons of Why Weed Eater Won’t Start 

Okay, your trimmer won’t start; here are some of the reasons as to why it is giving you headaches. There’s a school of thought that argues, wearing out is the precise reason as to why a weed eater won’t start. However, there’s more to trimmer troubles besides that. It could go a long way to prevent the gas powered weed eater or your trimmer from wearing out. Before you jump into broad conclusions, here’s what you ought to appreciate:

  • There’s not enough spark being generated by the trimmer’s magneto
  • The spark plug might be dirty or cracked
  • The fuel filter could be blocked or dirty
  • Improper venting
  • The carburetor could be clogged as a result of gum deposits or gas leftovers from winter
  • The spark arrestor screen could be blocked
  • A leaking bulb could cause the device not to start.

The Carburetor

The carburetor is a sensitive part of the engine, and understanding how it works is crucial. This approach could be a significant step towards appreciating some fundamental nuances of a trimmer’s operation and the reason as to why it’s giving you troubles.

The machine is equipped with a two-stroke engine, meaning that the weed eater is fitted with a carburetor. The function of the trimmer’s carburetor is to mix a mist of gasoline and air. This action is needed to form an explosive mixture, and it goes ahead to be burned in the trimmer’s engine to generate power.

Air drawn occurs into the engine by suction through a narrow tube in the carburetor. It flows through the trimmer’s venturi as it increases speed, causing the pressure in the trimmer’s engine to drop. This drop in the weed eater’s pressure draws fuel, which creates a mist of gas in the trimmer’s engine. The mixture in the weed eater’s carburetor flows out and is finally directed towards the cylinder, where it’s burnt to produce power.

Understanding this basic principle is enough to help diagnose why your weed eater won’t start.

This Is the ABC Approach If Your Weed Eater Won’t Start

These are our quick guidelines for the problem.

1.Check the Gasoline

Today the most used gasoline is ethanol-containing oil for trimmers. It could be the reason why your weed eater won’t start as it breaks down too fast as early as within thirty days. This calls for trimmer owners to stabilize their gas before putting their devices in the garage at the end of the season to ensure their weed eater starts the next time properly. The trimmer’s engine oxygen breakdown might prevent your weed eater from working properly if not stabilized.

2. Keep the Carburetor Clean and Replace Air Filters

The engine oxygen breakdown, gums, and other materials might clog the carburetor, and the weed eater won’t start. The reason is that clogging of the carburetor keeps fuel from reaching the weed eater’s combustion chamber and igniting the trimmer to start. You don’t want this for your trimmer. The approach is to remove the air filter and spray the carburetor cleaner into the intake. Once you’re done, replace the weed eater’s air filter and start your device.

A good practice is to avoid washing the air filters. Instead, do frequent replacements, and this will save you from problems.

3. Spark Plug Trimmer Checks

The use of low-quality oil can foul the trimmer’s spark plug, as is the case in most two-stroke engine weed eaters. Keep off the deposits from the trimmer’s electrodes as it might prompt the weed eater’s not to start. Start your weed eater always with good spark plugs, and replace the trimmer’s coils frequently.


That’s it, the perfect approach to a weed eater that won’t start. Remember to change the trimmer’s air filters frequently and keep the weed eater’s carburetor clean. Try these tips, and be sure to thanks us later for our acceptable guidelines to troubleshooting trimmers.
