Replacing Fuel Lines: Mtd 2-Stage Snowblower Maintenance Guide

If your MTD 2-stage snowblower won't start, you may need to replace the fuel line. This is a common problem with snowblowers, as they are often left unused for long periods, leading to fuel deterioration and carburetor clogging. To replace the fuel line, you will need a Phillips screwdriver and a socket and ratchet set. First, drain the fuel tank and disconnect the spark plug wire. Then, remove the electric starter switch and the engine shroud. Next, remove the fuel line by releasing the fuel line clamp and pulling it off the fuel filter. Install the new fuel line by connecting it to the tank and carburetor and securing it with the clamp. Finally, reinstall the engine shroud and reconnect the spark plug wire.

Drain the fuel tank and disconnect the spark plug wire

To replace the fuel line on an MTD 2-stage snowblower, you must first drain the fuel tank and disconnect the spark plug wire. This is a crucial step to ensure your safety and prevent accidental fires or injuries. Here's a detailed guide on how to do it:

Drain the Fuel Tank:

• Position the snowblower in a well-ventilated area before beginning any work.
• If there is fuel remaining in the tank, drain it completely. This step is essential for safety and to avoid spills during the replacement process.

Disconnect the Spark Plug Wire:

• Locate the spark plug wire, which is connected to the spark plug.
• Carefully pull the spark plug wire up and away from the plug. Set it aside, ensuring it doesn't accidentally fall back onto the plug.

By following these steps, you have now safely prepared your MTD 2-stage snowblower for further disassembly and fuel line replacement. Remember to wear appropriate protective gear and refer to the manufacturer's instructions or a qualified technician if you have any doubts during the process.

After completing these steps, you can proceed with confidence to the next stages of the repair, which include removing the electric starter switch, engine shroud, and other components to access and replace the fuel line fully.

Remove the electric starter switch

To remove the electric starter switch on an MTD 2-stage snowblower, you will need a socket wrench set with a ratchet and a Phillips screwdriver.

First, disconnect the spark plug wire by pulling it straight up and off the plug. Next, remove the two screws that secure the switch box to the engine. Pull the switch box away from the engine and let it hang by the power cord going to the starter motor. Now, remove the two starter motor mounting screws and gently pull the starter motor off the engine.

At this point, you should be able to access and remove the electric starter switch. Be sure to note how it is positioned so that you can reinstall the new one correctly.

If you are replacing the electric starter switch, be sure to purchase a manufacturer-approved snowblower part.

Remove the engine shroud

To remove the engine shroud, you will need to first pull off the choke and throttle knobs. You can then remove the acorn nuts that secure the carburetor to the engine. Next, remove the muffler shroud mounting screws. Finally, work the engine shroud off the carburetor mounting studs, leaving the primer hose and breather hose connected.

Step 1: Pull off the choke and throttle knobs.

Locate the choke and throttle knobs on your snowblower. These knobs are usually found near the engine. Grip the knobs firmly and pull them off.

Step 2: Remove the acorn nuts.

Identify the acorn nuts that secure the carburetor to the engine. Using the appropriate tool, carefully remove these nuts. This will loosen the connection between the carburetor and the engine.

Step 3: Remove the muffler shroud mounting screws.

Locate the mounting screws that hold the muffler shroud in place. Use a screwdriver or other appropriate tool to remove these screws. By removing these screws, you will be able to access the engine shroud more easily.

Step 4: Work the engine shroud off the carburetor mounting studs.

With the choke and throttle knobs removed, along with the acorn nuts and mounting screws, you can now carefully work the engine shroud off the carburetor mounting studs. Be gentle and take your time with this step to avoid any damage. Make sure to leave the primer hose and breather hose connected as you work.

By following these steps, you will be able to successfully remove the engine shroud on your MTD 2-stage snowblower, allowing you to access and replace the fuel line. Remember to refer to the repair guide or seek assistance from a qualified technician if you have any doubts or concerns during the process.

Remove the fuel line

To remove the fuel line, you will need to release the fuel line clamp and pull the fuel line off the fuel filter. Repeat the process to release the other end of the fuel line from the carburetor and remove the fuel line.

To do this, first drain the fuel from the tank or run the snowblower until the tank is empty. Position the snowblower in a well-ventilated area. Pull the spark plug wire up and off the plug. Remove the mounting screws and pull the starter switch off the bracket, letting it hang by the electrical cord.

Next, remove the engine shroud. Pull off the choke and throttle knobs. Remove the acorn nuts that secure the carburetor to the engine. Remove the muffler shroud mounting screws. Work the engine shroud off the carburetor mounting studs, leaving the primer hose and breather hose connected.

Now you can release the fuel line clamp and pull the fuel line off the fuel filter. Repeat this process to release the other end of the fuel line from the carburetor and remove it.

Install the new fuel line

To install the new fuel line, first, connect the new fuel line to the tank. Secure it with the fuel line clamp. Then, connect the other end of the new fuel line to the carburetor and secure it with the clamp.

Ensure that the fuel line is not twisted or kinked. Check that the fuel line is securely attached to both the tank and the carburetor.

Now, you can reinstall the engine shroud. First, pull off the muffler shroud. Then, remove the belt cover mounting bolts and pull off the belt cover. After that, remove the bolts from the red chute support bracket and pull the support bracket forward, releasing the control rod from the 4-way control rod receiver.

Next, remove the front muffler shroud mounting bolts. Release the wire control cables from the retainer clip and pull off the muffler shroud. Now, align the choke knob shaft and the 2 carburetor mounting posts with the openings on the engine shroud. Work the engine shroud onto the engine, ensuring that the breather hose passes through the opening and lines up with the rocker cover breather hose fitting.

Finally, slide the breather hose over the rocker cover fitting and secure the hose with the clamp. Reinstall the 2 acorn nuts to secure the engine shroud to the engine.
