Tecumseh Carb Fuel Inlet: Diy Replacement Guide

If you're looking to replace the fuel inlet on your Tecumseh carburettor, there are a few methods you can try. One method is to use a small self-tapping or sheet metal screw and thread it into the opening of the fuel fitting in the carburettor. Then, use a pair of vice grips to clamp onto the screw and, using a small hammer, tap on the vice grips to pull out the fitting. Another method is to use a 23/64 drill bit to first remove the original plastic fitting and then drill out the original metal portion of the fitting. You can then install a new Tecumseh fitting using red Loctite, ensuring that you position the new fitting in the same clock position as the original. If you're unsure about which method to use, it may be helpful to refer to online forums and communities dedicated to small engine repair and maintenance, where you can find advice and guidance from experienced individuals.

Removing the old inlet

To remove the old inlet on your Tecumseh carburetor, you will need to use a small self-tapping or sheet metal screw. First, thread the screw into the opening of the fuel fitting that remains in the carburetor. Then, use a pair of vise grips to clamp onto the screw. Using a small hammer, gently tap on the vise grips to carefully pull out the fitting from the carburetor.

Alternatively, you can try prying the old inlet off. However, this method may be more challenging as the metal part of the inlet is pressed into the carburetor body and can be difficult to remove.

Another approach is to use a 23/64" drill bit to first remove the original plastic fitting and then drill out the metal portion of the fitting. You must maintain a straight angle and pay close attention to the depth you are drilling. You will feel a difference and notice a speed change in the drill when you reach the right depth.

Once you have successfully removed the old inlet, you can proceed to install the new fuel inlet.

Using a small self-tapping screw

To replace the fuel inlet on a Tecumseh carburetor using a small self-tapping screw, follow these steps:

First, you will need to remove the old fuel inlet. Use a small self-tapping or sheet metal screw and thread it into the opening of the fuel fitting that remains in the carburetor. Then, use a pair of vise grips to clamp onto the screw. Using a small hammer, gently tap on the vise grips to pull out the fitting from the carburetor.

Now that the old fuel inlet has been removed, you can install the new one. The new fuel inlet should come with a plastic part attached. Pry or twist this plastic part off the new fitting. You will be left with a metal part that you can now press into the carburetor. Be sure to position the new fitting in the same clock position as the original fitting. You can use red Loctite to secure the fitting and ensure it is pressed in straight.

Alternatively, you can use a 10-32 tap to cut threads inside the original metal fitting. Then, use a 2" long bolt with a socket that fits over the inlet (an 11 or 12mm socket should work). Place a washer and nut on the bolt and thread it into the threaded tube. Tighten the nut against the socket to create a puller that will allow you to remove the old fitting. As before, you can use a 4" c-clamp or a similar tool to press the new fitting into the carburetor, being careful not to apply too much pressure and crack the plastic.

With either method, the new fuel inlet should now be securely installed, and you can reconnect the fuel line and start your engine.

Using a pair of vise grips

To replace the fuel inlet on a Tecumseh carb using a pair of vise grips, follow these steps:

Firstly, use a small self-tapping or sheet metal screw and thread it into the opening of the fuel fitting that remains in the carburetor. Ensure that the screw is tightly secured in the opening. Once this is done, you can take your pair of vise grips and clamp them onto the screw. It is important that the vise grips are tightly clamped onto the screw, as this will be the main source of grip and stability when removing the fuel inlet.

Now, take a small hammer and begin to gently tap on the vise grips. This action will slowly but surely begin to pull out the fuel fitting from the carburetor. Continue tapping until the fuel inlet is completely removed from the carburetor. It is worth noting that, although it may seem counterintuitive, the use of a vise or press to remove and replace the fuel inlet typically does not result in damage to the plastic elbow.

When it comes time to install the new fuel inlet, simply follow the steps outlined in the Tecumseh manual or seek guidance from a professional or experienced hobbyist.

Drilling out the original metal portion of the fitting

The next step is to create threads on the inside of the remaining metal portion. This can be done with a 1/4"-20 tap. It is important to do this carefully to avoid damaging the threads. Once the threads are created, you can use a 1/4" bolt, 1/4" nut, and a washer to remove the metal portion of the fitting. Place the bolt into the fitting and tighten the nut until it comes into contact with the shank of the bolt. Continue tightening until the fitting is removed.

It is important to note that this process may require a significant amount of force, and it is crucial to take the necessary precautions to ensure your safety and avoid damage to the carburetor.

Now that the original metal portion of the fitting has been removed, you can install the new fuel inlet. Simply press it into the carburetor using a vice or press, being careful not to damage the plastic elbow. Coat the exposed portion of the shank with Loctite grade A and press it in until the shoulders come into contact with the carburetor body.

By following these steps, you can successfully drill out the original metal portion of the fitting and install a new fuel inlet on your Tecumseh carburetor.

Installing the new inlet

Now that you have successfully removed the old inlet, it's time to install the new one. Here are the steps you need to follow:

• Prepare the new inlet: Remove the new plastic piece from the new fitting. You will only be installing the metal part of the new inlet.
• Positioning: Ensure that the new inlet is positioned correctly. It should be in the same clock position as the original fitting. This is important, so take your time and double-check before proceeding.
• Installation: You can use a vice or press to install the new inlet. Place the metal part of the new inlet into the carburetor and press it in firmly. Alternatively, you can use a 23/64" drill bit to drill out the original metal portion of the fitting and then install the new inlet using red Loctite.
• Avoid damage: Be careful not to apply too much force during installation, as the new inlet can be fragile and may break if excessive force is used.
• Test: Once the new inlet is installed, check for any leaks or damage. If everything looks good, you can proceed with the rest of the carburetor rebuild or reassemble your equipment.

Remember to consult a professional or a repair manual if you are unsure about any steps or if you encounter any problems during the installation process.
