How to start a toro lawn mower. When you take your Toro lawn mower out for a run and it doesn’t start, the first thing you think about is why.
This is one of those frustrating problems that someone without much experience dealing with this sort of thing can run into.
Fortunately, there are a few basic steps you can try before heading to your local garden shop to see if they have any help or expertise to offer in order to fix things up.

We will explain why your Toro mower won’t crank, and then we will show you how to get it back up and running again so you can enjoy cutting your grass tomorrow.
Clogged Carburetor
Carburetors sometimes will get clogged, which is why a lawnmower should only be stored for no more than two weeks without a full and thorough cleaning.
The longer you leave fuel in to sit, the higher the odds that it may evaporate or collect impurities over time.
If this happens, the carburetor can become clogged with this thick liquid, which makes starting your engine nearly impossible.
To combat this issue, first, use carburetor cleaner to clean out the system; then remove any parts that need replacing or rebuilding.
Defective Spark Plug
Inspect the spark plugs for wear or damage. If the porcelain insulator is chipped,
An electrode is frayed or damaged, or there are heavy deposits on either the electrode or porcelain housing, replace the spark plug.
To see if a spark plug has been working properly, use a tester to check whether there is a strong glow between the terminals when you turn on the car and start the ignition process.
If there is no spark, then it may be possible that it has been defective in some way. In this case, you should have it replaced as soon as possible.
Faulty Fuel Pump
The fuel pump has three ports: the gas in port, the gas out port, and the pulse port. The pulse port is connected to the engine crankcase by a small rubber tube that has two valves, one to let fuel in and the other to let it out.
When there’s an air pocket in the crankcase, pressure builds up inside of it and pushes on the diaphragm inside of the fuel pump. This creates a vacuum that moves gas through the line towards your car’s gas tank.
If there’s too much oil in your engine, it seeps into these parts meaning there’s not enough space for air to pressurize as quickly so performance becomes diminished or it won’t work at all.
Replace Ignition Coil
The spark plug sends voltage to the ignition coil. The ignition coil sends a spark of electricity to the combustion chamber, causing an explosion inside the cylinders.
When an engine misfires, it may be due to dysfunctional spark plugs, worn-out wires, or faulty grounding on its parts.
However, if you have confirmed that your spark plug is working properly and there is no fault in your wires or ground circuit, test the ignition coil’s functionality by checking whether it causes a meltdown on a spark tester.
Replacing a defective spark plug with another one will not solve the issue you need to replace the faulty ignition coil too.
Broken Flywheel Key
The flywheel key is a small metal piece that fits into the crankshaft and engages with the other metal parts inside the generator to increase its speed.
In the case of a sudden stop, if this part gets snapped in half, it can’t engage properly with other metal parts in order to keep increasing the engine’s speed.
First off, remove your generator’s flywheel and check whether or not the flywheel key broke in two. If it did, you’ll need to replace it before trying to start your engine again.
Dirty Fuel Filter
A clogged fuel filter might be caused by old fuel. Old fuel can be clumpy and sticky, which may clog the fuel filter and make your mower hard to start.
Release the pressure of the fuel tank by loosening the cap on top of it and then draining all the used gas out of it. Replace your fuel filter with a new one, being sure to follow any instructions supplied with the replacement.
Rewind Pulley and Spring issue
When the starter rope is pulled and released, the rewind spring will recoil onto a pulley. If the rewind spring is worn out or broken, you won’t be able to recoil it.
As a result, you won’t be able to start up your lawnmower. Many replacement starters come in assembly with the recoil cable, so if yours breaks down you should consider replacing it as well as the cable.
Problem with Recoil Starter Pulley
The starter pulley winds up the starter rope when the engine is not being used. If the pulley is broken, it will not be able to wind up and rethread the starter rope.
As a result, you won’t be able to change your motor’s elevation, essentially rendering it unable to start.
If at any point you notice that the pulley is damaged or in some way not functioning properly, we suggest having it replaced as soon as possible by a tool company like ours!
Remove Pre-Cleaner
If a lawnmower is hard to start, it’s possible that the air filter is clogged up. But this problem is typically due to an over-abundance of foreign debris in the machine.
The pre-cleaner is located after the lawnmower engine and prevents any matter from getting into the engine itself.
If a homeowner can hear the mower running yet it’s not properly cutting grass, you should immediately check to make sure the pre-cleaner isn’t blocked.
