If you’re frustrated with your lawnmower’s engine, you’re not alone. Surging is a very common problem. This often happens after the mower’s engine has been running for some time. Or, it can occur when the fuel level drops. You can find some relief by adjusting the choke and throttle, but if this doesn’t help, you should contact a service professional.
Another common cause of the problem is a blockage in the fuel supply. If this happens, it’s likely to be a dirty or faulty carburetor. To check the carburetor, remove the muffler and loosen the screw at the bottom of the governor arm. The governor shaft is connected to the bottom “clip” of the engine. Rotate this counter-clockwise to position the governor shaft on top of the governor spool.
If the problem persists, consult your lawn mower’s manual to see if you can adjust the carburetor. Most mowers have two screws that allow you to change the idle speed and fuel-air mixture. If you’re unfamiliar with the carburetor system, consult your owner’s manual for instructions on how to adjust it. If the settings are not consistent, the machine may be out of tune.
If the carburetor is the problem, your lawn mower may be running overheated. To fix this issue, you’ll need to clean it out. After cleaning it, make sure the air filter is free of dirt and debris. Insufficient air can cause the engine to rev too high or too low. (getzonedup.com) Using the correct lawnmower air filter can improve engine performance and make it run more smoothly.
The next step is to check the air filter. It is critical to check the air filter for any clogging. Insufficient airflow will reduce the engine’s normal speed. If the air filter is clogged with debris, the engine will rev excessively. If the air filter is clogged, the governor spring can be adjusted to increase tension or reduce resistance. Then, you can test your lawnmower by turning it on and off without the gas filter.
The most common cause of high revving lawn mowers is a blockage in the fuel supply. Other reasons include dirty/faulty fuel or a bad spark plug. A blockage in the fuel supply can also lead to surging. In the end, you’ll need to adjust the governor in order to prevent it from overheating. You can adjust the governor in the engine by loosening the screw at the bottom of the engine.
If your lawnmower is surging, you should inspect the air filter. The air filter should be clean and have an open airflow system. If the airflow is obstructed, it will result in high-revving lawnmowers. To fix this problem, you can consult the manual or contact a maintenance specialist. In most cases, you can make the necessary adjustments on your own.
If you notice your lawnmower revving excessively, you may have an air filter that’s too dirty. The lack of air can make your mower run too fast or too slow. A dirty air filter can also cause your lawnmower to run too slowly. If the filter is dirty, you can replace it to correct the problem. If the spark plug is clean, it may be blocked.

Low gas level is the most obvious cause of high lawn mower revs. A low fuel level can also cause your lawnmower to run too slowly. In this case, it is better to call a maintenance expert and have them look at the problem. Alternatively, you can adjust the carburetor screw to match the engine’s needs.
