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 :
Often your nose can make the diagnosis: Flooded engines reek of unburned fuel. Park the mower on level ground, and wait about 15 minutes for the gas to evaporate. Then try starting it again, with the choke off.
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. The easiest way to tell if your engine is flooded with gas is to remove the spark plug.
Carburetor leaks can be caused by bad gaskets, an sticking float and other defects. If fuel is leaking from the bottom of the carburetor, the float bowl gasket might be dried out or missing. Check the connections to the fuel filter and to the filter housing. If any of the fuel lines are dry or cracked, replace them.
When trying to start a flooded engine, the end goal is to re-establish the fuel-air balance in your vehicle. To do so, simply open the hood of the car and let the excess of fuel evaporate. After waiting for some minutes, try starting your car again, keeping your foot away from the gas pedal.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
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.
To fix a flooded engine, you basically want to get the air to fuel ratio back to its usual balance. You can first try to simply let the excess fuel evaporate. Open your hood and wait a couple minutes before you try to start your car again. And when you do start it back up, make sure you aren`t pushing on the gas pedal.

If your engine is flooded with too much fuel and not enough air, your engine`s spark plugs may no longer be able to ignite the mixture, causing you to lose power. Fortunately, fixing a flooded engine is a pretty simple process, but it can be an irksome inconvenience—one that`s easily avoided with the proper know-how.

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?

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

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.
