How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The most common cause of your mower engine not starting after a long period of storage is stale fuel, but there are many other possible reasons there could be a fault. Our advice is to contact your local lawn mower servicing provider for a professional inspection.
In a nutshell, start by unscrewing and removing the carburetor cap, which is near the primer button. Then spray the carburetor with a carburetor spray, and while you`re at it spray the cap as well and clean it out with a paper towel or cloth. Screw the cap back on, and you`re all set!
An airlock is one of the common causes why your mower won`t start after running out of fuel. An Airlock occurs when air replaces fuel in the fuel lines. As you refill your fuel tank, you could push the air towards your mower`s carburetor, which keeps the new fuel from reaching the engine.
Problems arise in cold weather, because cold air is oxygen-rich, as you can imagine throws the ratio way off. Without the choke, the engine gets too much air for the amount of gas the engine receives. We call this a lean condition. A mower just won`t start or starts and stalls right away when the AFR is too lean.
If your mower loses power and then won`t restart, it might be due to dirty air filters. This is a simple problem to check and fix. Make sure the filters are clean and in good working order and try again. If this was the problem, it should start up again easily.
One way to remove the gas is to use either a hose to siphon off the gas or a baster/pipette to remove the gas from the lawn mower gas tank to a gas can. Alternatively, the fuel line connecting the fuel tank to the carburetor can be disconnected at the carburetor and fuel emptied into a gas can.
Place a large bar in the flywheel and gently rock back and forth to loosen. If this doesn`t work – or if you are uncomfortable with placing a pry bar in the flywheel – try putting the tractor in a high gear and rocking the rear tires back and forth. Once the flywheel is loosened, do a quick tune-up on the carburetor.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.

Mower won’t start
This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.
Hope it helps.

Ryobi troubleshooting Recently bought the two set package of 18V lithium batteries however the tool will not work. It was working however it has stopped . Tried two different batterie , both fully charged ,with no results.
The motor may have overheated and burned open. Use a multimeter to check resistance across the battery contacts in the tool with the switch closed. If it reads open, the motor has failed.

Bad carburetor your old fuel jammed up the jet so it won’t get fuel and if it does it will start and shut off So replace the carb or try to clean the jet and run non oxy fuel only
My dls 3500 mower will not start at all, I charged the battery but the engine wont even turn. All the wiring and fuses seem to be ok
I had the same problem. I replaced the wiring harness for a short fix, corrosion in the terminals that connect to ignition switch. This worked for a while. Then replaced ignition switch this also worked for short time. Now I just open the hood to reach behind the ignition switch and wiggle wires while turning key to start until it starts keep wiggling to get good contact. If it won’t stop after it starts, wiggle wires after you turn the key to off. It will stop.
Poulan blower was running – ran out of gas – put gas in – won’t start- primed – won’t start – let sit – won’t start-took cover off – sprayed starter fluid in carb – won’t start- -(very little stutter) won’t start-set overnight – repea -twon’t start-wits end !!!
Does it use a fuel and oil mixture?You probably did that.
Try removing the spark plug and cleaning it with a wire brush or some emery cloth.Make sure you have spark by connecting the plug wire and resting the plug on the metal motor block.
Do not hold the plug in your hand ,if you have no spark you may have a bad magneto.
Have a john deere sabre turn key won’t start thought battery was dead charged battery still won’t start jump start with car battery it will start then . try to engage reverse with blades running it shuts off. shut down tractor won’t start again .I,m thinking wiring not grounded but where or replacement switch somewhere.give best advise.
Some mowers have a mowing reverse safety switch. That safety will kill the mower if you try to reverse with the deck engaged. Some mowers even have an override button that has to be held while backing up. As for the battery thing, no matter how much you charge a bad battery you will not get it to start a mower if it has a bad cell or two. I would use a multimeter to check battery voltage, but the end result would still be the same, replace the battery.I hope this gets you going again.
My mower will start but won't stay running – Toro LX466 22HP Lawn Tractor 13RT61RH244
I am going to respond 2 times to this post. The first reply will be generic things to check.
First off check the oil level and make sure it is serviced to full.
If your having a lack of fuel (runing lean) you will need to check fuel flow at the carb fuel mainfold. It should fill a spray paint can lid in less than 10 seconds but teting flow rated of the main fuel line. If you have poor flow here… you need to check the fuel filter and the fuel tank outlet port for obstructions.
Good Fuel flow still shutting off…. remove the carb float bow and clean the debris from the bow’ and the treaded area where the fuel solenoid mounts Additionally you will have to again remove the main fuel line and spray carb cleaner in the float needle area to flush out any debris through the fuel hose connection.
For the second response I need to know which engine is installed on your mower by MODEL number if you can locate it. (there are 3 engines) At least try to find the engine model number. If you can not locate it Brand and HP of the engine (I assume 22 hp) Thanks for choosing FixYa,
