Ryobi Tiller Parts

Primer and Hose Assembly This is a primer and hose assembly, and it is used on various lawn equipment. The assembly comes with two parts. The first is the hose which is almost 5 inches long, and less than a 1/4 inch thick. The second part is the primer bulb or primer pump, and that is 2 inches long, and 1 inch wide, with a round bulb head. Together, the primer and hose assembly fill the carburetor with fuel to give your machine a quicker start. After time, your hose will crack and your primer will lose elasticity. Both will have to be replaced when this happens. Before starting this repair make sure to drain the fuel from the tank, and remove the spark plug.

Fuel Line and Filter This fuel line filters the fuel in the tank as it pushes into the carburetor by the primer bulb. If your carburetor is not getting fuel, ports get clogged, or the fuel line is leaking, then replacing this part will solve these problems. It is important to replace it as soon as damage is noticed because clogging can result in your engine not starting. For this repair, you will need the following tools: torx/Phillips drivers, long screwdriver, long-nosed pliers, long screwdriver, cutters or scissors, and two-cycle engine oil. For this repair, first remove the retainer ring from the fuel line and insert it through gas cap opening. Next, thread the fuel line through the hole in the bottom of the fuel tank and pull the line through to firmly place it against the tank wall. For the last steps, put the retainer ring on the fuel line and press the ring firmly against the external side of the fuel tank wall. Lastly, attach it to correct line on the carburetor.

Fuel Return Line This is a fuel return line, and it is used with various outdoor lawn equipment. Fuel travels through the return line into the carburetor, and from the primer bulb/pump into the fuel system. The line returns the extra fuel back into the tank. This part will crack and become brittle over time. If your fuel line is leaking, you will need to replace it. Before you begin repair work on your equipment make sure you drain the fuel from the tank, and remove the spark plug.

Air Filter This air filter fits lawn and gardening tools to keep dust and debris from damaging and contaminating the carburetor. If dirt builds up, it can even effect the engine from working properly. To replace your filter, remember to place it in a plastic bag with some oil. Rub the oil into the filter and once you remove it, squeeze the excess oil out. *Please note: this is sold individually.

This spark plug is used for lawn and garden equipment engines, such as trimmers, hedge trimmers, leaf blowers, cultivators, edgers, tillers and power brooms. The spark plug delivers electric current from an ignition system to an internal combustion engine, basically igniting the fuel in the engine. With use, spark plugs can become dirty and fouled, if this is the case then replace your spark plug to solve this issue. Repair tip: you will need to gap your spark plug. Follow instructions in the manual provided by the manufacturer for further guidance.
