Experienced gardeners share their insights in answering this question :
You might of flooded it with too much choke, which is easy to do in cold weather because the fuel doesn’t have enough time to vaporize.

Let it sit for a while with the choke off. If you have starter fluid give a shot of that with the air cleaner off and no choke to see if it starts.

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.
Your Mower Won`t Start:

Other possible causes include: Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas.

A common issue is a clogged carburetor from stale gas. Using a fuel stabilizer keeps fuel fresh and the carburetor from gumming and varnishing. Third step, check the ignition system with a spark tester. Step four, replace the spark plug and reconnect the spark plug wire.
Hard hot starting mower issue is most likely caused by a failing coil, but there are other possibilities: Plug faulty. Engine flooded. Low oil level.
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.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Old and new gas should not be mixed for a variety of reasons, the major ones are; The old gas degrades over time it should not be added because it has already lost it`s combustibility. It can cause sputtering. It might fail to fire it up.
Fuel stabilizer keeps gasoline, especially gas with ethanol (E10, E15), from going bad in a vehicle being stored for a half-year or more. Dry gas is the generic term for an additive that works to keep water in the tank or fuel lines from freezing. (Drygas is the brand name of one such product.)
Expired gasoline can damage internal components of your carburetors, deteriorate fuel lines and seals, and cause a varnish build up that could clog small fuel ports which are necessary for your machine to start and run. Fresh gasoline is essential to the proper starting and running of a machine.
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.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

2009 Self propelled Troy Built with briggs and stratton won’t start. It ran fine until I added (fresh) gas in it. The last time this happen the repair shop said it was the gas and they changed the spark plug. When I got the mower home I asked the repair shop about the gas that was still in the tank and they said you may want to change it. That leads me to believe they didn’t change any of the gas that was in it, but now it runs. What did they do? So is there something I can do? I changed the spark plug still no go. I poured a little gas in carb and it ran for the amount of time gas was in carb, then it died.

thanks,

JM

ANSWER : Drain the gas (not because of what shop said). Unscrew the brass bolt that holds the float bowl onto the bottom of the carburetor. Be careful, there is a small washer in between the bolt head and the bowl bottom. Remove the bowl. Clean out the bow. Now, clean the brass bolt. There are holes in the bottom and in the sides where the smooth part is. Use no metal wires. Clean with tooth picks if necessary. Reassemble. This is a real common problem, especially if no in-line fuel filter is used. You may want to install one and don’t let old gas evaporate in the mower.

Hello, My 31 cc troy built blower won’t start. It’s got spark. When I pulled the brand new plug it appeared to be completly dry. I sprayed ether in the cylinder and put the plug back in and it started for a brief moment. Not sure what’s going on. Any help would be much appreciated. Thanks in advance.

My troy built starts but will not speed up enough to use even after it warms up. It is 2 years old but only has 3-4 hours of use on it . Can you help me?
ANSWER : Is it 2 cycle or 4 cycle? Meaning, does it take plain gas, or mixed gas?Clean the plug, clean the carb with either choke cleaner (4 cycle) or wd-40 (2 cycle) by spraying it into the choke hole after you take off the air filter.You may also want to spray some of the choke cleaner or wd-40 into the gas tank with the gas to help clean out the whole fuel system.Only use choke cleaner for 4-cycle regular gas units. For mixed gas, use wd-40 in place of choke cleaner.Try to start it and then go back and forth from half choke to full choke until it starts picking up.
