A carburetor may dry up after prolonged periods of inactivity, causing problems starting the engine. If this happens, the carburetor will need to be primed. Priming is adding fuel to the carburetor. Most lawnmowers have a priming bulb so you don't have to pour gas into the carburetor manually. This component is usually a small rubber button, which suctions fuel from the tank. To activate it, simply press it several times. If it fails to draw fuel, then a primer bulb may be needed. Primer bulbs can deteriorate due to old age, repeated use, and exposure to chemicals and the environment. For worry-free machine compatibility, choose this Primer Bulb & Hose Assembly made by MTD. It will work with trimmers, leaf blowers, and string trimmers from MTD, Bolens, Yard-Man, Craftsman, Ryobi, and Huskee. The assembly comes with one primer bulb and one hose.

A carburetor needs fuel to produce the required combustible mixture of air and gas. To get fuel, the carburetor draws the liquid directly from the fuel tank. Any excess fuel will be returned to the tank through the fuel return hose or fuel return line. In addition to providing the path, a fuel line is also responsible for preventing over-pressurization, as well as vapor lock. A fuel return line is constructed from a thick rubber material that is also fuel resistant. However, it may still become brittle and crack due to regular wear and tear. Usually, a broken fuel return hose results in symptoms such as engine misfires, loss of power, carburetor flooding, fuel leaks, and hard starting. A brand-new replacement is available here.

A lawnmower’s fuel line or a fuel hose brings the fuel from the tank to the carburetor. It is made of durable translucent plastic material. When pushing the primer bulb, the gas from the tank will travel through the fuel line and to the carburetor. Once there is enough fuel, any excess will go to the return line and into the tank. Fuel lines are made from sturdy rubber or plastic. Over time the fuel line can crack and begin to leak. There are few symptoms of a broken fuel hose. One of the easiest ways to tell is if the hose has visible exterior cracks. Other warning signs include fuel smell and fuel leaks. Installing a new fuel line is easy and doesn't require any tools. Detach the old fuel pipe and insert the new replacement.
