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.
First remove the fuel line from the carburetor and plug it so fuel does not run out. On the very bottom of the carburetor bowl there will be a small brass cover screw, using a flat screw driver, open this screw and allow all gas to drain from the carburetor system. Next, close the screw and reinstall the fuel line.
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.
The most common cause of this type of problem is when the fuel filler neck`s inner tube comes off of the neck itself. You will need to have the filler neck removed to check to see if the inner tube was knocked off from someone trying to get fuel out of tank with a siphon hose and managed to knock the hose off.
Gas leaks around the lawn mower air filter can indicate your engine valves are not working properly. If your engine has a fuel shut-off valve, ensure that this valve is closed when the engine is not in use.
The fuel and air will not mix as well as when your carburetor is balanced. This results in oil and gas spills from the exhaust of the lawn mower. The next time you see black liquid coming out of lawn mower exhaust vents, then this could be due to an imbalanced carburetor.
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.
Lining your gas pipes with epoxy will help seal the leaks. Once applied, let the epoxy hold and cure for approximately one hour. The reason you are using epoxy to seal the leaks is to avoid replacing the whole system. However, if you can replace the leaking pipe with a new one, do so to avoid future leaks.
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).
The fuel is drawn into the carburetor by the vacuum created on the downstroke of the piston. As air accelerates through the Venturi, it creates a low pressure area and velocity of the intake air increases. This rapid acceleration causes the air and fuel to mix and vaporize.

Hello. Thanks for using fixya. First thing i would do is make sure it has gas in the fuel tank. If that’s ok. I would replace the spark plugs next. Could be that they are fouled out causing the no start problem.

I have a cub cadet 2165 I just put in a new battery and it is slow turning over any ideas?
If battery is good and everything is hooked up right. Most likely could be the pto clutch bearing. Not the bearing on the pulley but on the clutch inside. Had the same problem, took the spark plugs out got it free. Turned over easy with plugs out, Started right up after and then burned up my bearing. Don’t burn up bearing. If do field assy. For that is 200$ if you can get away with just that. Otherwise 350-400$ for full assy.

Sounds like another carburetor blockage. Remove the carburetor and clean out all the orifices in the main jet. Also, check the float for leakage.
