Carburettor and Fuel Injection Cleaner is supplied in a 400ml aerosol that enables fast cleaning of carburettors and other similar engine components without the necessity to dismantle. It can be used to clean carburetors, injector throttle bodies, plates, chokes, butterflies, jets, and linkages. Fuel injector cleaner can also be used to clean gummed-up carburetors in small engines. However, it is important to note that carburetor cleaner should not be used to soak injectors as it can damage the o-rings and brittle the plastic.

What You'll Learn
Carb cleaner dissolves gum in carb jets and orifices
Carburettors can become clogged with gum, varnish, and dirt over time, which can lead to poor engine performance, reduced fuel efficiency, and potential engine damage. A carburettor cleaner can be used to dissolve gum in carb jets and orifices, improving engine performance and fuel economy.
There are different types of carburettor cleaners available, such as add-in-tank and spray cleaners. The main difference between add-in-tank carburettor cleaners and fuel injector cleaners is that carburettor cleaners focus on dissolving gums inside the carb jets and orifices, while fuel injector cleaners dissolve carbon/deposits formed near or surrounding the pintle.
To clean a carburettor using a spray cleaner, such as Gumout® Carb/Choke & Parts Cleaner, first remove the air cleaner and clean the outside of the carburettor and all of the linkage. Avoid spraying electrical connections. Then, with the engine running, spray the cleaner into both ends of the choke valve shaft while working the choke by hand. Spray down and around the carburettor throat to remove deposits from the throttle plate area, but be sure not to spray down the carburettor throat with the engine off.
Another method for cleaning a carburettor is to soak it in a cleaner solution. Follow the time recommended in the product's instructions, and then use a soft-bristled brush to clean all parts, including the jets, float bowl, and throttle body. Rinse and dry the carburettor thoroughly, and then blow out all passages with compressed air. Finally, reassemble the carburettor and install it on the engine, adjusting as necessary.
It is important to note that some carburettor cleaners may not be safe for all materials. For example, one user reported that Gumout® Carb/Choke & Parts Cleaner caused swelling in rubber o-rings and needles, so it is important to read the product's instructions and warnings carefully before use.

Fuel injector cleaner dissolves carbon deposits near the pintle
The PEA-based fuel injector cleaner is a highly effective solution for dissolving carbon deposits that have formed near or around the pintle. This type of cleaner can also gradually soften and break down carbon buildup at the back of intake valves, which is often beyond the capabilities of ordinary carb cleaners.
Over time, contaminants in the fuel tank, fuel lines, or the fuel itself can restrict injector flow and cause issues with the pintle. Foreign particles such as rust can accumulate within the injector filter, reducing fuel flow and potentially preventing the injector pintles from seating properly. This can lead to overfuelling of cylinders, resulting in reduced engine performance and potential damage to the engine, piston, or rings.
Fuel injector cleaners with quality additives can help improve combustion and restore engine performance. Introducing solvents to the engine can effectively remove carbon deposits and improve the condition of injector pintle baskets. However, it is important to note that a completely effective chemical cleaning of injectors may not always be possible, especially in high-heat-soak engines or those with injectors clogged by sediments.
For a more thorough cleaning, injectors may need to be physically removed from the engine and cleaned without the use of caustic chemicals. Off-car cleaning equipment, such as ultrasonic baths, can achieve total injector restoration by immersing the injectors in a non-flammable ultrasonic cleaning agent.
It is worth noting that some engines with fewer than 100,000 miles may not require additional cleaning solutions, as top-tier gas stations already add additives to their fuel to maintain a clean fuel system. However, for older vehicles or those using discount gas, the use of a fuel injector cleaner with PEA can be beneficial in maintaining engine performance and fuel efficiency.

Fuel injector cleaner can be used on carburettors
Aerosol carburettor and fuel injection cleaner products are available, which can be used to clean carburettors and other similar engine components without the need to dismantle them. These products can clean carburettors, injector throttle bodies, plates, chokes, butterflies, jets, and linkages, and they help reduce engine emissions.
The main difference between carburettor cleaner and fuel injector cleaner is that carburettor cleaner focuses on dissolving gums inside the carb jets and orifices, while fuel injector cleaner dissolves carbon/deposits formed near or surrounding the pintle. However, some sources claim that there is no real difference between the two, and that carburettor cleaner is simply marketed towards older vehicles.
To use fuel injector cleaner on a carburettor, a small amount (1/2-1 oz) can be added to the fuel tank. The engine should then be started, or cranked 20-50 times if it will not start. This method can help to clean the carburettor and improve engine performance.

Carb cleaner can be used on injectors
Carburetor cleaners and fuel injector cleaners are both used to improve engine performance and fuel economy. The main difference between the two is that carburetor cleaners focus on dissolving gums inside the carburetor jets and orifices, while fuel injector cleaners "dissolve carbon/deposits" formed near or surrounding the pintle.
However, some people argue that there is no real difference between the two types of cleaners, and that either one can be used to clean the fuel system components. For example, one user on BobIsTheOilGuy.com stated that "there are very few mechanics that have ever seen a carburetor on a daily driver," and that "you can use either one." This sentiment is echoed by customers of the Gumout 800001373 Fuel Injection/Carburetor Cleaner, with one customer stating that they "use [the product] in [their] car AND mix it with [their] mower gas......keeps everything clean."
It is important to note that while carburetor cleaners and fuel injector cleaners can be used interchangeably, regular maintenance of fuel injectors is crucial to prevent any issues. This includes changing out the fuel filter, using a quality name brand gasoline with the proper octane rating, and using fuel additives to avoid buildup.
In summary, while there may be some minor differences between carburetor cleaners and fuel injector cleaners, both types of products can effectively clean fuel systems and improve engine performance. Therefore, carb cleaner can indeed be used on injectors.

Carb and fuel injector cleaner can be used without dismantling the engine
Carb and fuel injector cleaners can be used without dismantling the engine. These cleaners are supplied in aerosol form and can be used to clean carburettors, injector throttle bodies, plates, chokes, butterflies, jets, and linkages. They help reduce engine emissions and improve engine performance.
Carburettor cleaners focus on dissolving gums inside the carb jets and orifices, while fuel injector cleaners dissolve carbon/deposits formed near or surrounding the pintle. However, some people argue that there is no real difference between the two, and both will clean the fuel system components.
When using a carb cleaner, it is important to note that it should not be used to soak the injectors, as it can eat away at the o-rings and brittle the plastic. Instead, it can be sprayed on and then gently wiped away with a clean lint-free rag. Fuel injector cleaners, on the other hand, can be mixed with gas and used to soak the ends of the injectors, which can then be scrubbed with a soft-bristled toothbrush.
It is also recommended to replace the injector-to-manifold grommets and fuel rail hoses when cleaning the injectors to ensure a tight seal and prevent fuel leaks. Additionally, look for PEA-based fuel injector cleaners as they can help gradually soften and break down carbon build-up.
