Things to Consider Before Buying
If you're buying a carburetor cleaner for the first time, you may want to consider a few key points before settling on which cleaning product you invest in. Firstly, you need to assess and understand how far you want to go with your carburetor cleaning.
Scale of Job
Do you want to do a quick job with minimal effort? Then a pour-in fuel additive would be your best bet.
If you’re confident with a little disassembly, but don’t actually want to remove and strip the carburetor then a spray cleaner is also a great idea, as it can be used with the carb in-situ.
For a more thorough cleaning of carburetors—especially those that may have been out of commission for several years, you’re more likely to want to do a complete strip and soak of the carburetor parts to ensure that all remnants of any deposits are completely removed. For this purpose, a chemical dip is your best option.
Looking for a quick fix, or are you prepared to sit it out overnight? Do you need your car running on the road in five minutes, or do you have some time to spare? These are all vital questions to consider when you’re selecting a good quality carburetor cleaner for your usage. Some claim to work in seconds, while others are better suited for overnight soaking. Choose the right substance for your schedule.
Condition of Carburetor
Your choice will likely depend on how badly gunked-up the carburetor in question is. If it’s an engine that has seen regular use, and only has a few minor noticeable hiccups then a quick clean via either a pour-in additive or spray carb cleaner is a great and cost-effective way to deal with the problem. But, if the engine hasn’t been cleaned for some time, or has been out of commission, then you might be better off investing in a stronger cleaner, with a proven ability to get tough grime off.
Chlorinated vs Non-Chlorinated
Chlorinated Carburetor cleaners are banned in California due to their non-compliance with Volatile Organic Compounds (VOC) regulations. But chlorinated cleaners are known to be the most effective solution for tough deposits that may have built up over the years. Non-chlorinated cleaners are considered to be less harmful and less toxic to the environment, and won't dry as fast. They also have the advantage of being safer for use around plastics and rubber.
While most carburetor cleaners are safe for use, it’s advisable not to inhale the fumes that are emitted. If you’re particularly sensitive to such, or are even allergic to any known chemicals, it’s always a good idea to double check the label before buying.
Frequently Asked Questions
What does a carburetor do?
The carburetor is where air and fuel are mixed before they are combusted inside the cylinder. For this reason, having a clean and efficiently working carburetor is essential for smooth running, better gas mileage and reliability. And if you're handy with your own maintenance, cleaning a carburetor is a cinch—provided you have the right carburetor cleaner!
Why does a carburetor need cleaning?
An engine’s carburetor is an essential part of the combustion process. It is where air and fuel are mixed before combustion. Some of the remnants from combustion, mostly known as carbon, can make their way into the carburetor chamber, and over time clog up the carburetor. That’s where periodic cleaning is advised, as these deposits will, over time, reduced efficiency.
How often do I need to clean my vehicle’s carburetor?
A car’s carburetor may only need cleaning once every year or so, but there’s no harm in increasing those intervals. If you notice a problem with the smooth running of the engine, or if you feel there is a loss in power, and your engine is equipped with a carburetor, then cleaning it is a good option to eliminate this.
Do all engines have carburetors?
No, most modern engines use fuel injection. But many classic and “youngtimer” models do have carburetors, as they were once the most common method of fuel delivery in engines. However, it is commonplace for some certain smaller engines, like those found on lawnmowers, go-karts, mopeds, and some motorbikes, to feature carburetors.
Why does my carburetor need frequent cleaning?
You may find that your car’s carburetor needs frequent cleaning. If cleaning is necessary at intervals greater than 12 months it’s very likely there’s an underlying issue that should be addressed. This could include your driving style, the quality of fuel in your area, and the tuning of your car’s engine and carburetor. Engines that do not combust properly will likely end up with greater carbon deposits. If this is your worry then a trained mechanic should be able to give your engine a tune-up to restore efficiencies and reduce the rate at which your carburetor needs cleaning.
My engine hasn’t run for a long time. Should I clean the carburetor before starting?
Cleaning the carburetor of a long-dormant engine is a prudent step. Fuel can often “expire” and when it does so it can foul areas within an engine. By cleaning out the fuel system before the first fire-up you give yourself a better chance of success, and will likely reduce your time attempting to crank and get fuel moving through the system again.
