Replacing The Fuel Line On Your Earthquake Chainsaw

If you're having trouble starting your Earthquake chainsaw, it could be time to replace the fuel lines. Chainsaw fuel lines can clog, crimp, or crack over time, restricting fuel flow and preventing the engine from starting. Luckily, replacing the fuel lines on an Earthquake chainsaw is a straightforward process that you can do yourself with the right tools and safety precautions. Here's a step-by-step guide to help you get your chainsaw running smoothly again.

Remove the cylinder cover and air filter

To remove the cylinder cover and air filter, you'll need to get an appropriately-sized screwdriver and remove all the nuts on the cylinder shield. Craftsman chainsaw models typically have 3-4 nuts on the shield. Once the nuts are off, you can remove the cover. Take out the air filter and check if it can be replaced after washing it with fuel. You may need to replace the fuel filter if it is dirty. Also, disconnect the spark plug.

It is important to remember that this process may differ for other chainsaw models. Always refer to the owner's manual for specific instructions.

Disconnect the spark plug

Disconnecting the spark plug is an important step in maintaining your chainsaw and ensuring it is in the best condition. Here is a detailed, step-by-step guide on how to do this for your Earthquake chainsaw:

Firstly, you will need to gather the right tools and materials. For this task, you will require a combi spanner with a large opening or any other appropriate tool, depending on the size of the spark plug. It is always recommended to refer to your chainsaw's operator's manual for the correct spark plug size.

Now, let's begin the process:

• Access the spark plug by taking off the cover. This will expose the spark plug, allowing you to work on it.
• Once the cover is removed, carefully pull the cap and wire off the spark plug. This will disconnect the spark plug wire, as mentioned in the repair guide.
• Before proceeding further, inspect the top contact of the spark plug for any signs of corrosion. If there is corrosion, clean it thoroughly with a wire brush. It is important to ensure that the area is free from dirt and debris as well.
• At this point, you are ready to remove the spark plug. Use the combi spanner and turn it anticlockwise to unscrew the spark plug.
• With the spark plug removed, inspect it closely for any damage. Check for cracks or carbon deposits, and also examine the contacts on the electrode.
• If there are carbon deposits, use a wire brush to clean them carefully. This will ensure that the spark plug is free from any debris or buildup.
• If the spark plug appears to be in good condition without any damage, and you have cleaned the electrode and contact post, it is now time to reinstall it. Thread the spark plug back into the engine, making sure it is firmly seated using the socket wrench. Be careful not to overtighten it.
• Finally, reconnect the cap and wire to the spark plug post, ensuring that it clicks into position. This will ensure a secure connection.

Remember to always refer to your chainsaw's operator's manual for specific instructions related to your Earthquake model. Additionally, it is important to wear appropriate safety gear and work in a well-ventilated area when performing any maintenance on your chainsaw.

Remove the air filter housing

To remove the air filter housing of your Earthquake chainsaw, you will need to follow a few steps. Firstly, ensure that your chainsaw is switched off and is placed on a flat surface. It is important to work with safety and caution when dealing with a chainsaw.

Begin by removing the two bolts that are holding the air filter housing in place. You can use a screwdriver to do this. Once the bolts are removed, carefully pull out the air filter housing and keep it aside. Make sure that you do not misplace the bolts, as you will need to put them back later.

The throttle linkage is attached to the backside of the air filter housing. Before removing it, carefully inspect and take note of how it is attached. You can also take a picture on your phone to help you remember how to reassemble it later.

Now, you can move on to the next steps of replacing the fuel line, which may vary depending on your chainsaw model.

Take out the fuel filter

To take out the fuel filter from your Earthquake chainsaw, you will first need to empty the fuel tank. This is important for safety reasons.

Once the tank is empty, you can begin the process of removing the fuel filter. You will need to use a special tool or your fingers to take out the old fuel filter. Straighten a piece of coat hanger and bend a hook on the end. Feed this through the mouth of the tank and carefully remove the fuel filter. Cut the fuel line if necessary to remove the filter.

Now, pull out the fuel hose from the tank unit to completely remove the fuel filter. It is important to be gentle and careful during this process to avoid any damage to the surrounding components.

With the old fuel filter removed, you can now install a new fuel filter. Simply fit the new fuel filter onto the end of the fuel hose and then refit the hose into the tank unit. Ensure that the fuel filter is secure and properly connected before continuing.

Finally, refill the fuel tank and you're done! Remember to always exercise caution when working with fuel and only proceed if you are confident in your abilities to complete the task. If in doubt, consult a professional technician for assistance.

Remove the carburetor

To remove the carburetor from your Earthquake chainsaw, you will need a 7/16-inch socket driver. This is the tool required to remove the two mounting nuts that secure the carburetor to the engine.

Before you begin this step, you should have already disconnected the spark plug wire, removed the air filter, and emptied the fuel tank.

Now, with your 7/16-inch socket driver, remove the two mounting nuts. Pull the air filter housing off the carburetor. Then, carefully pull the carburetor from the engine block, sliding it along the mounting studs. Be careful not to bend the throttle linkage or damage the gas lines.

For accurate reassembly, it is recommended to take digital photos of the throttle linkage on the carburetor and the gas line connections.
