Lawn Mower Runs Rough – Easy Wat to Fix

If your lawn mower is running rough, it’s likely due to one of four common issues: stale fuel, a dirty air filter, Spark plugs that need replacing, or an uneven blade. Any of these problems are easy to fix yourself with a little time and effort.

Top Reasons Lawn Mower Runs Rough

If your lawn mower is running rough, there are a few things you can check to try and troubleshoot the issue. First, make sure that the spark plug is clean and free of debris. You can also check the air filter to see if it needs to be cleaned or replaced.

If neither of these seem to be the problem, it’s possible that the carburetor needs to be adjusted or replaced.

Common Causes of a Lawn Mower Running Rough

One common cause of a lawn mower running rough is dirty spark plugs. Over time, deposits can build up on the spark plugs and impede their ability to create a spark. This can cause the engine to misfire and run roughly.

Another common cause is an accumulation of grass clippings and other debris around the engine. This can restrict air flow and cause the engine to overheat.

How Can I Tell If My Lawn Mower is Running Rough

Your lawn mower is designed to provide a clean, level cut to your lawn with each pass. But if it’s running rough, it can leave your lawn looking uneven and unkempt. There are a few things you can check to troubleshoot a running rough lawn mower.

First, check the air filter. A dirty air filter can restrict air flow to the engine, causing it to run rough. Clean or replace the air filter as needed.

Next, check the spark plug. A fouled spark plug can cause an engine to run roughly. Clean or replace the spark plug as needed.

If those two things don’t fix the problem, then you may have an issue with carburetion. Make sure that the carburetor is getting enough fuel and that the mixture of fuel and air is correct. You may need to adjust the carburetor or have a professional tune it up for you.

Easy Ways to Fix a Lawn Mower That’S Running Rough

If your lawn mower is running rough, it’s important to diagnose the problem and then take the appropriate steps to fix it. Otherwise, you could end up doing more harm than good. One of the most common reasons for a lawn mower to run rough is that the spark plug is dirty or fouled.

A spark plug that’s covered in oil or debris can prevent the spark from igniting the fuel, which will cause the engine to run rough. To clean a dirty spark plug, simply remove it from the engine and scrub it with a wire brush. If the spark plug looks damaged, you’ll need to replace it.

Another common issue is stale or old gas. Gas that’s been sitting in your lawn mower for awhile can gum up the carburetor and prevent the engine from running properly. To fix this, simply drain out all of the old gas and refill with fresh gasoline.

If your air filter is dirty, it can also restrict airflow to the engine and cause performance issues. To clean or replace a dirty air filter, consult your lawn mower’s owner’s manual – each model is different. Finally, if your lawn mower isn’t starting at all, there could be an issue with the battery or starter solenoid.

If you suspect either of these problems, take your lawn mower to a qualified repair shop for further diagnosis and repairs.
