This particular air cleaner filter is made for gasoline-powered trimmers. If any piece of lawn equipment kicks up more dust and particulate than a lawn mower, it is a trimmer. Trimmer line, unlike a mower, does not maintain a constant angle. Because trimmers are also frequently used as edgers, they fill the air with dust and debris. While air cleaner filters are made of durable material, they eventually become clogged with yard waste to the point that they simply cannot be cleaned. Users know that this is happening when the trimmer will not run smoothly, or it cannot be started at all when no other problem is indicated. The filter is replaced by removing the back cover and discarding the old filter. Before putting it in place, work a few drops of two-cycle oil into the new filter. This will help the foam capture more airborne pollutants. Reverse the process to install the new filter. When the time comes to replace the air cleaner filter, it is imperative that the new filter be an OEM certified part that has been manufactured to the same specifications as the original.This part may be used on string trimmers, tillers, and leaf blowers by Craftsman, Ryobi, Troy-Bilt, Yard Machines, MTD, Huskee, Bolens, and Yard-Man.

Few parts fulfill as many roles on lawn mowers and other landscaping power tools than the cover screw. This screw serves to attach metal housing parts, assemblies, and shrouds to one another on equipment such as power vacuums, snow blowers, edgers, tillers, hedge trimmers, lawn tractors, leaf blowers, grass trimmers and cultivators. As these are extremely durable metal screws, they seldom fail under ordinary use. It should be noted, however, that they are most often used at connection and pressure points. Stresses at these junctions sometime loosen screws, causing them to be lost or occasionally resulting in stripped threads. It's also occasionally the case that these screws are lost during repair or routine maintenance of yard equipment because of their small size. Users should make sure to consult their owner's manuals for replacement steps and any special instructions. Because of their small size and the ease of losing them during repair work or maintenance, it's recommended to keep a supply of appropriately sized screws on hand. Most importantly, when replacing a part make sure to use a genuine OEM replacement part. They are manufactured according to the specs of the original parts and are perfect replicas.

This fuel line assembly is created for use with string trimmers and is used to bring gasoline to the small engine in a lawn and garden tool. As the string trimmer is used, the fuel line assembly can start to break down, which may result in cracks in the fuel lines or discoloration. This can cause the fuel line to stop working the way it should, which will affect the performance of the trimmer. If the fuel lines are no longer the correct color or seem brittle, a replacement is likely needed. The line can be pinched to see if there are any visible cracks. In some cases, the primer bulb will no longer seal the way it should and will create more air than expected when priming the trimmer. Another sign that the fuel line assembly is damaged is lower power when someone uses the throttle. This is a genuine OEM part that comes directly from the manufacturer. It is a single part that is designed for use in Troy-Bilt, Craftsman, MTD, and Yard-Man string trimmers. No additional tools are needed to make the replacement.

This part is sold individually and is sourced directly from the manufacturer. "

The Fuel Pick Up Assembly is an OEM part for Husqvarna outdoor power equipment, including chainsaws, trimmers, and blowers. This assembly is responsible for drawing fuel from the tank to the carburetor, ensuring the engine receives a steady supply of fuel for optimal performance.

Over time, the fuel pick up assembly can become clogged or damaged due to debris in the fuel, exposure to ethanol-blended gasoline, or regular wear and tear. If the fuel pick up assembly is compromised, it can lead to poor engine performance or difficulty starting the equipment.

Symptoms of a bad fuel pick up assembly include:

• Engine not starting or hard to start
• Engine stalling or running inconsistently
• Reduced power or performance
•  Visible damage or clogging in the fuel line

This OEM Husqvarna part ensures proper fuel delivery and compatibility with your outdoor power equipment.

The Fuel Line is an OEM replacement part for Husqvarna outdoor power equipment, such as chainsaws, trimmers, and blowers. This component is essential for transporting fuel from the tank to the carburetor, ensuring that the engine receives a steady supply of fuel for optimal performance.

Causes of a bad fuel line can include regular wear and tear, exposure to fuel and environmental elements, or physical damage from mishandling or improper storage. Over time, the fuel line can become brittle, crack, or clog, hindering fuel flow.

Symptoms of a bad Fuel Line include:

• The engine failing to start or running inconsistently
• Visible cracks or leaks in the fuel line
• Fuel odor or visible fuel leaks around the equipment
• Reduced engine performance or stalling during operation

A primer bulb is a small rubber button-like component. This essential part pulls fuel through the fuel line and helps fill the carburetor with the right amount of fuel. Pressing the primer bulb will start the fuel flow and combustion. The primer bulb makes starting the engine easier, and without it, undue stress will be placed on the carburetor. There should be a slight resistance when pushing it and it should pop back out after depressing it. If the primer bulb is cracked or is not creating proper suction, replacement is necessary. The rubber material will eventually harden and crack over time. Stale fuel can also cause primer bulb deterioration. To replace a primer bulb, it is best to consult the equipment's manual for diagrams that show the bulb's placement. This is an OEM part made from high-quality material and is manufacturer-approved for use as a replacement. It can be used in lawn maintenance equipment such as string trimmers, leaf blowers, chainsaws, and pole pruners from brands like Craftsman, Husqvarna, Weed Eater, Poulan, and Poulan Pro.

This is a replacement carburetor for Husqvarna string trimmers and is also used on some Craftsman models. It consists of an aluminum body with a bright blue choke and cherry red primer bulb. Engines rely on a mixture of fuel and air for proper operation. In a small engine, the fuel and air mix inside the carburetor. This is achieved with a series of small channels, which release a fine mist of fuel into a vortex of air. When one of these channels gets clogged, it can negatively impact engine performance. Carburetors can often be cleaned with a commercial carburetor cleaning spray, but this is sometimes not sufficient to clean a badly clogged carburetor. In this case, other measures such as hypersonic cleaners can often be effective, but they’re not always worth the cost. The alternative is replacing the entire carburetor, which can be done using this kit. This is an OEM part sourced directly from the manufacturer, and it is sold individually. A heat shield is also included with the kit.
