Ryobi Lawn Mower Won’t Start

Ryobi Lawn Mower Won’t Start. People prefer Ryobi lawnmowers over regular gas lawnmowers because they are earth-friendly and contribute to green living. Unfortunately, you will find yourself encountering the occasional issue when it comes time to start the mower up.

This should not be overlooked or ignored because a variety of causes may contribute to this problem and restarting the mower is difficult for some users who have experienced these issues.

The reasons for why your Ryobi lawnmower won’t start can vary from one user to another, but some common factors that might contribute to why the product isn’t starting up properly include issues such as:

Why is my Ryobi Lawn Mower won’t start. Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug.

 Bad Or Old Gasoline

There could be old fuel in the carburetor float bowl, which happens to be one of the most common causes why fuel engines don’t start.

After some time certain ingredients in the fuel evaporates, leaving behind a thick and sticky substance that can clog up your carburetor and prevent it from functioning as intended.

If your carburetor is clogged, clean it with carburetor cleaner or replace it with an entirely new part.

Carburetor problem

The carburetor might be clogged. Clogs in carburetors are often caused by leaving fuel in the lawnmower for a long period of time.carburetor problems

Over time, some of the ingredients from the fuel used may evaporate, leaving behind a mustier substance that can clog up the carburetor and prevent the engine from starting.

If you don’t want your fuel to get so musty or stick to something, store it properly and clean your mower on occasion to help everything run smoothly again.

If cleaning or replacing your carburetor doesn’t work, you may need to rebuild or replace it completely.

Faulty Spark Plug

Inspect the end of the spark plug for signs of wear or damage. If you notice any cracks on the insulator, evidence of burning on an electrode, or a carbon buildup, you might need to replace your spark plug.

To determine if your spark plug is working properly, use a tester to see if there is a strong spark coming from it when the engine turns over.

If there’s no spark, you can assume that your brand new and expensive replacement needs to be replaced as well because it’s broken.

Defective Fuel Filter

It’s possible that the fuel filter might be clogged. A common cause of clogging a fuel filter is when there is old gas left in the lawnmower.

When gas sits, various elements will evaporate, leaving behind sticky substances that are hard to get through the fuel filter and into the engine where it can combust.

If this is suspected to be the case, drain all of the gas from the tank, replace the old fuel filter with a new one and then add fresh gas.

Ignition Coil Failureignition coil failures

The ignition coil works with a spark plug to produce an electrical spark that ignites an air-fuel mixture in the cylinder of your engine.

Your ignition coil may be defective if your lawnmower isn’t starting properly or randomly cutting out.

Before you go replacing the ignition coil, make sure the spark plug is working first by taking it out.

Checking that there are no problems present like cracks or chipped insulators. If everything checks out, test the ignition coil with an ignition coil tester or multimeter and replace it if necessary.

Key to Flywheel

The flywheel key might have sheared in half. The flywheel key is a small metal piece that fits into the crankshaft and engages with the flywheel.
If the lawnmower engine stops suddenly due to hitting a hard object, the flywheel key breaks in half to prevent damage to the engine.
If the flywheel key is broken, the lawnmower won’t start. To determine if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, replace it.

Malfunction Of Rewind Springs

In case your starter spring is broken, you may have trouble starting your engine. The start spring recoils the starter rope onto a pulley when you pull the starter lever.

If the starter reel spring is broken, the rope won’t be able to recoil onto the pulley, which makes it impossible to start your engine.

If your rewind spring is broken, it’s best to replace it. Many rewind springs can be replaced individually but if yours needs replacing, we recommend replacing the entire recoil starter assembly for easier starter access and improved performance.
