FUEL PUMPS
Small motors use a simple gravity feed system to fill the floating container. Larger engines, such as lawn tractors, require a higher flow of gas. In addition, the gas tank may be located lower than the carburetor. Then a fuel pump may be required. These pumps may be electric, use a camshaft rod to operate a diaphragm in the pump or rely on the carburetor suction through a diaphragm-operated hose (a diaphragm is a flexible material drive pushed back and towards Ade Lante to fuel pump.
Typical faults in pumps are a loss of voltage in the pump, a clogged filter in the pump, a disconnected air hose, a perforated diaphragm, or the pump component intake.
Low oil level
Larger engines with an electrical system sometimes have a low-oil floating switch. This prevents the engine from starting and being damaged if the oil in the sump is below a threshold level.
