When Your Brush Cutter Does Not Working

When you get outside to start your string trimmer, weed whacker, or Brush Cutter, none of them will turn over. If you’ve attempted to start it a few times but it won’t, and you smell like gasoline, you’ve probably flooded it. This is the most likely explanation. Before you make another attempt, give the gasoline some time to evaporate by waiting around ten minutes.

If you’re still having trouble starting it, I’d be happy to walk you through the steps we take on our farm whenever anything like this occurs and how we resolve the issue using our Stihl FS85 Brush Cutter. Our systems have been up to date since the publication of this article. Both a Stihl FS350 and a Branco 52A are in our possession. Use the instructions outlined here as a reference in combination with the instruction manual that came with your brush cutter or string trimmer. The information provided here applies to most string trimmers and brush cutters.

Let’s go through each of these procedures one by one to figure out the issue and how to fix it so that you can return to cutting grass and weeds.

Examination of the Spark Plug

Take out the spark plug; if there is gas on it, it is a good sign because it indicates that the gas is making its way through.
If your engine isn’t performing as well as it should, the problem can be with the spark plug getting clogged up. The condition of your spark plugs might also be affected by the cleanliness of your air filter.

If your spark plug is unclean, you can clean any accumulated deposits around the electrodes using fine emery paper. The gapping instrument that measures the distance in a spark plug should be set to 0.02 inches (0.5mm). This is the recommended standard. If the space is too huge, a pair of pliers can bring it down to a more manageable level. If you have a different brand of brush cutters, the handbook should be checked to see the appropriate gap. You can find the user manual for your device online if you no longer have it.

It is recommended that the spark plug be replaced after around 100 hours of operation; however. But if yours is approaching that threshold, this is a simple and low-cost solution to the problem. It is advisable to have a backup available to swap out the broken one and continue working.

Performing an Inspection of the Air Filter

The next thing you need to do is inspect the filter in your air conditioner. It is easy to believe that cutting grass and weeds shouldn’t cause them to become clogged. But if you have been working in a dry and dusty atmosphere, it may be the cause. Remove the dust with a bit of tapping; if yours is felt, you can wash it. Before putting it back into the machine, ensure it has thoroughly dried off.

If the cutting you are doing generates a lot of dust, this is something. So that you will want to check regularly. If you clean the air filter, the coughing and sputtering noise that your machine may be making will be eliminated. You may improve the performance of your machine by ensuring that the air filter is cleaned and replaced regularly. As a preventative step, it is a simple action to keep from dealing with more severe issues.
Dust particles are a typical issue because we live in an area with high winds and close proximity to dunes. As a result of this, the air filter in our building is examined frequently.

Concerns Regarding the Brush Cutter’s Carburetor

One of the things that will be checked as the last resort is the carburetor. If your brush cutter has been sitting idle for an extended period. So the gasoline may have accumulate in the carburetor, causing it to become clogged. When the gasoline starts to evaporate, it leaves behind a residue that is sticky and gummy.

Because the gasoline around here is mixed with alcohol and contains grit. But the carburetor on our farm is the primary source of trouble for us. Even though we are using a funnel that has a tiny filter, there is still the possibility. So that some material will pass through and jam the jets in the carburetor.
