It should not cause this type of problem. I suspect the diaphram in the carburetor is getting stiff and brittle. This prevents the fuel being pulled into the carburetor. If you can prime the unit and make it run, then you may need to have the carburetor rebuilt or replaced.
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 :
If the chainsaw won`t start, or starts and then stops and you find the spark plug wet with fuel mixture, it means that the engine is flooded (you will probably smell petrol). It happens when too much fuel enters the combustion chamber, possibly because you have pressed the primer many times.
The carburetor might be clogged and needs to be cleaned.
A chainsaw`s carburetor mixes air and fuel to start the internal combustion engine. If fuel has been left in the engine for too long, it can become sticky and clog the carburetor, preventing it from starting. If the clog is minor, clean out the carburetor.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
If it is difficult to start the ride-on mower, the most common reasons include: Old fuel; make sure to use fresh fuel, especially after winter storage. Spark plugs might be dirty or damaged. How to examine and replace a spark plug on your ride-on mower.
If your chainsaw still starts and then stops working, check the air filter. Clean or replace the air filter if it is dirty or damaged. Another reason that your chainsaw starts and then stops working could be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.
The two most common reasons a chainsaw won`t idle are a blocked air filter and an idle screw out of adjustment. Other possible causes include: Dirty Air Filter. Idle Screw out of Adjustment.
Restricted Fuel Lines
The engine can be suffocated from gasoline when at peak demand for fuel if there is any slight restriction or debris in the fuel lines. The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle.

Mower won’t start
ANSWER : 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.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

My Husqvarna 323L trimmer will no longer start after I added fuel and cranked it several times with the switch set to off. When I realized then corrected the switch, it still would not start. Before now, it always started on the first or second pull. I have checked for compression, spark and fuel. All seems fine, it just won’t start. The fuel is fresh and is the same fuel I used with no problem in my blower. Any ideas? Thanks!
ANSWER : Let it sit 2 hrs. then try to start it as usual.

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.
