The problem with any lawnmower is long idle times. If you are not in the Miami or Hawaii region, "the end of the season" and "the beginning of the season" are quite active concepts for you. In between, unpleasant things can happen to the fluids and consumables inside your lawnmower. If your machine won't start after the third attempt, things with a high probability are bad. But we'll tell you quickly what to do if your lawnmower won't start.
Refuel and Clean the Lawn Mower Tank
Firstly, check the total level of gasoline in the tank. If necessary, use a flashlight to illuminate it. Gasoline of any type also tends to deteriorate rather quickly. If the lawn mower won't start, carefully drain the old gasoline into a special container and pour new liquid into the mower. It can help in a lot of cases.
Remove Debris from the Mower Deck
In fact, dried grass can be a serious problem, blocking key mechanisms of the lawnmower. Start by using a scraper or a putty knife to scrape off any grass clippings and debris stuck to the underside of the deck if lawn mower not starting. Be gentle to avoid damaging the deck surface. Continue with special brushes, and finally, if necessary, finish the process with a tight wash. Push mower not starting yet? Keep looking for the cause.
Replace the Lawn Mower Air Filter
The air filter plays a critical role in keeping your engine running efficiently by filtering out dirt and debris from the air before it enters. If left idle for long periods of time, it can become clogged, restricting airflow and preventing the engine from running smoothly. Your lawnmower wont turn over without checking the filter for contaminants and replacing it at the slightest hint of them.
Examine the Spark Plug
To check the spark plug, you may need a special tool that checks for the spark itself. Fortunately, this consumable is inexpensive, so if your mower wont start, you can simply replace the spark. Use another special tool to remove the old spark plug. Install the new one, turn it back a little, and then slowly and carefully screw it into the mower.
Ensure the Fuel Filter is Unclogged
Yes, lawn mowers usually have several filters, one of which is the fuel filter. It prevents dirt from entering the carburetor, where it can clog the fuel system. If you suspect that your push mower won't start because of this specific filter, it’s best to leave its inspection and repair to the professionals.
Clear the Fuel Cap Vent
If your mower not starting or keeps stalling, the problem may be that you need to clean the fuel cap vent. This part of the lawn mower is responsible for the smooth flow of gasoline from the gas tank to the carburetor. If it is not working properly, gasoline vapors accumulate. If there is excessive accumulation, the operation of the lawn mower may become incorrect. Here you can easily do it yourself. Unscrew the fuel cap vent and start the lawn mower. If the problem persists, buy a new fuel cap vent and replace the old one with it.
Check the Safety Release Mechanism Cable
This element is designed to make it completely safe to use the lawnmower. If you release the safety bar, the engine will simply stop. It can really save you from a tragic accident if you suddenly pass out on the lawn. If the mower turns over but wont start, this specific element may be the problem. The mechanism consists of a bar that is connected to a metal cable, which in turn is connected to the engine ignition coil. You should check the tension of the entire mechanism. The cable should move freely and not jam. If you feel that something is wrong, you will have to make a replacement. Such cables are sold both in specialized stores and in home goods. It is a little more difficult to replace the cable. This will require some technical knowledge. If necessary, also consult professionals.
Verify the Flywheel Brake is Properly Engaged
The flywheel provides engine smoothness through inertia. Your lawn mower will not start if there's anything wrong with it. A fully engaged flywheel brake can make the pull cord difficult to operate. Ensure the brake pad contacts the flywheel properly and that nothing is obstructing the blade movement. If the flywheel's key is sheared, it may have hit an obstruction. Replacing the flywheel key is possible but requires disassembling the mower.
Identify When to Seek Professional Repair
In any case, when you feel that there is a possibility of losing the official warranty on the equipment, or that there is a risk of injury during repair, it is better to turn to experts. Just ask them: Why is my lawn mower not starting, what spares we need to change and save yourself a headache.
