Where to place the wrench

To replace a carburettor fuel filter, you will need to place a wrench where the fuel line connects to the carburettor. Take the line off and unscrew the part the line connects to. There is a small filter inside. You can also cut the fuel line and install a plastic filter.

If the carburettor has been sitting for a long time without being drained, some of the passages could be gummed up with dried fuel residue or lacquer. In this case, you should consider getting a carburettor rebuild kit and replacing all the gaskets.

There is a sintered brass filter inside the carburettor at the fuel inlet. To access this, you will need to remove the hose clamp and the nipple with a socket (13/16”). The fuel inlet line is at the top left of the carburettor. It is held on with a band clamp. You can put an inline filter anywhere in that hose.

If the carburettor has been running without filters, the screens could be gummed up. In this case, you should follow the install manual for your model of carburettor.

Next, remove the hose clamp and nipple with a socket (13/16”). Cut the fuel line and install a new filter. You can put an inline filter anywhere in the hose. Make sure to choose a filter that is compatible with your vehicle and carburetor.

It is important to note that you should also inspect the inside of the carburetor. If it has been sitting for a long time without being drained, some of the passages could be gummed up with dried fuel residue or lacquer. In this case, you may need to get a carb rebuild kit and replace all the gaskets.

Cleaning the carburettor

To clean the carburettor, you will need to remove the carburettor from the engine. This will allow you to access the inside of the carburettor and clean it thoroughly.

First, locate the fuel line that connects to the carburettor. Use a wrench to loosen the connection and remove the fuel line. This will give you access to the carburettor.

Next, use a socket to remove the nipple that connects the fuel line to the carburettor. Be careful not to damage the threads on the nipple, as this will make it difficult to reinstall the fuel line later.

Once the nipple is removed, you will be able to see the inside of the carburettor. If the carburettor has been sitting for a long time without being drained, there may be dried fuel residue or lacquer inside. Use a carb cleaner to blast out the passages and remove any built-up residue.

You can also use a carb rebuild kit to replace all the gaskets and seals inside the carburettor. This will ensure that the carburettor is clean and functioning properly.

Finally, reinstall the nipple and fuel line, making sure to tighten the connections securely. Test the engine to ensure that the carburettor is functioning properly and that there are no fuel blockages.
