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 fuel tank on your chainsaw is a plastic reservoir that stores fuel. The plastic can occasionally become cracked, and when this happens, fuel can leak out. There are several places on the fuel tank that can cause leaks, such as the grommet, the gasket, or the fuel cap.
If you notice gas leaking from the bottom of your car when you fill up, it`s most likely coming from the fuel tank vent hose. This hose is responsible for allowing air to enter the fuel tank as it`s being filled up, and if it`s damaged or not properly connected, gas can leak out.
Defective Gas Tanks

The majority of fuel-tank related explosions or fires occur because the tank ruptures upon impact, which then causes fuel to leak and pool underneath the vehicle. Fires and explosions that result from fuel leakage often have catastrophic consequences for vehicle occupants.

There are three main causes of residential gas leaks: poor or degraded fittings/connections between the gas line and a specific appliance, lack of proper appliance maintenance and appliance malfunctions.
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.

In general, silicone is not compatible with petrol. There are, however, some silicone-based products that are specifically formulated to resist fuel. SS-300, a room temperature vulcanising silicone sealant, is a notable example.
Using epoxy glue is the easiest way to seal a plastic fuel tank, but it sometimes fails after a short time. If using a plastic welder for the first time, practice before attempting to seal the plastic gas tank. The rental store should be able to work with you to ensure that you have no problems.
Everyone`s done it – but if you quickly switch the burner off within a minute or two, it`s not particularly dangerous. Some estimate that leaving a gas stove on without a flame for 10 to 15 minutes can increase gas concentration to explosive levels.
For each fuel, ignition occurs only within a certain range of concentration, known as the upper and lower flammability limits. For example, for methane and gasoline vapor, this range is 5-15% and 1.4-7.6% gas to air, respectively. An explosion can only occur when fuel concentration is within these limits.
Symptoms include: over reving, overheating, stalling on acceleration, failure to idle, and worst of all, an engine seizure if the problem is neglected. When an air leak occurs, it often puzzles users and even some saw shop technicians because the symptoms of an air leak are varied.
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.

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?
