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 :
One of the more common questions we get concerns either the overwhelming smell of gas coming from the carburetor or fuel leaking out of the bowl or overflow. Both conditions are typically caused by a stuck or worn float needle valve.
LEAKS FROM THE CARB FUEL OVERFLOW
Interestingly, if your fuel tank vent is blocked or not working, then this will cause air pressure to build up, forcing fuel into the carb. This excess fuel eventually gets pushed out of the overflow pipe.
If the lawn mower leaks gas the carburetor bowl gasket on the bottom of the carburetor might be dried out or missing. If the leak is coming from the bottom of the carburetor, try replacing the carburetor bowl gasket.
Gas leaking from the carb overflow is common when a bike sits for long periods of time. Gas can come out the carb overflow when the bike is tilted. This is most often caused by a float that is set too high in the carb bowl. Incorrect float height will also affect jetting, so you need to fix this right away.
The fuel pressure regulator is leaking fuel into the intake manifold and may have even filled the engine oil with gasoline. You should have the fuel pressure regulator replaced and the oil and filter replaced.
In many cases, what causes your car to spit out gas is in the fuel filler vent not ventilating the fuel. When the fuel is not properly ventilated, pressure may start to build in the gas tank. This pressure results in the car spitting to reduce the pressure in the tank when the fuel nozzle is removed.
If you overfill your tank, it can cover the vapor intake hole with liquid gas, which can then be sucked into the charcoal canister. This can damage the canister and possibly other parts of the system, which will cause the car`s check-engine light to come on and could potentially cost hundreds of dollars to repair.
If you accidentally spilled gasoline on the hot engine or exhaust, there could be a fire, an explosion, or both. Gasoline fumes are highly flammable and can be dangerous when inhaled so don`t store your lawnmower in a building where open flame or sparks are present and never store your mower in your home or basement.
Most commonly a result of improper starting, “flooding” results from various causes, including over-priming, closed choke, stuck valve, gummed carburetor, or immediately trying to restart an automatic choke engine.
Sometimes, your car may have the following symptoms: an irregular idle, poor fuel economy, lack of power, stalling, or a high-pitched hissing sound from the engine.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
Over time, the carburetor may develop cracks due to the vibration and heat of the engine. If the carburetor is cracked, it will leak fuel. Inspect the carburetor for cracks or corrosion. If the main body of the carburetor is leaking, you will most likely need to replace the carburetor.
note: cars with carburetors — typically those made before the 1990s — will normally give off a gas smell at times. this is due to the way carburetors are designed, with a float bowl that houses some residual fuel after you shut the car off.
To check fuel delivery, remove the fuel line where it enters the carburetor and use a length of rubber hose to direct the flow into bottle or similar container. Fuel should pulse out in strong spurts if your engine is equipped with a mechanical fuel pump (electric fuel pumps are more of a steady stream).

Just bought a used leaf blower, homelite, gas leaks out of the gas tank, where the gas tube fits into it.
ANSWER : “top of the gas tank where the gas tube fits into the tank”
I assume you’re describing the gas tank cap. if so, the o-ring is missing from the gas tank cap. You can find those at hardware stores.

Need to know what carb screw adjustment need to be set at weedeater starts for about 4-7 sec then shuts down put new hoses on checked gas filter and cap checked out ok. i pump the ball about 10 times ,pull cord &starts for about 4-7 sec then shuts down,like no gas or electrical problem. i played with the screw settings & dont know where they shoould be set at . had carb all apart ,put in new plug doesnt seem to matter what i do it does the same thing . any thoughts?also when it starts the motor will rev up when u hit the gas and when it shuts down the gas hose from the tank is still full of gas
ANSWER : If there is a choke adjustment you should set that at full until the trimmer warms up, don’t touch the gas. Then repull start at half choke, don’t touch the gas either at this time. Then start at no choke, and then set your idle on the carberator with the adjustment screw. Also don’t push the primer bulb so many time you will cause the spark plug to get flooded and drown out the spark, which is exactly what is happening.

Do I need gas and oil mix – Poulan Super 250a Chainsaw Plate
ANSWER : I think Poulan uses a 40:1 ratio to one gallon of gas, however I have always used 50:1 the same as my sthl saws with no issue. I would rather have more oil mix that to little.

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?

Ryobi gas I changed the primer bulb and gas lines on my machine and now it doesn’t get any gas to the carb. The primer bulb pumps it up, when i take the gas line loose at the brass fitting on the bottom of the carb, gas spews out. If I pour gas straight into the carb, it will start and run until that gas is gone, then it goes dead. It’s like the gas goes to the fitting but won’t go into the carb, even if you pull the trigger like you were running the thing. Any suggestions? Gasless
ANSWER : Check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. also check the primer bulb for pin holes and proper seating/seal. if that doesn’t work have the carb repaired at a service center or replaced.

My tractor stalls like it is starved for gas although the gas tank is full. I,ve changed the fuel filter and the gas cap. I’ve cleaned out the gas tank, gas lines, and the carburetor bowl. The problem seems more acute when the gas tank is full or near full. At this time to alleviate the problem, I blow through the gas cap and the fuel filter fills with gas and it runs good again. But as soon as the fuel filter has no more gas, of course, it stalls until I blow on the gas cap. As the tank gets down to about 1/3 full, the engine runs OK. What else could cause this condition?
ANSWER : I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block – remove the hose and spray carb cleaner in the hose wait a few mins and try again – its a vacuum for the carb
