Methyl Ethyl Ketone (MEK)
The degreasing and cleaning nature of MEK makes this chemical a main ingredient of carburetor cleaners.
Gumout is the best carburetor cleaner for those in a hurry. If you need to dislodge gunk and don't have time to take apart your carburetor to let it soak for a day, use an aerosol cleaner.
Position the tip of the aerosol can into the center of the carburetor and spray directly into the running carburetor. Doing this while the carburetor is running allows the cleaner to penetrate inside and clean the carburetor's throat and remove deposits that exist in the lower throttle plate.
Spray liberally with carb cleaner – trying to direct the cleaner into the jets – and leave to soak for a few minutes. Use an air line (or a can of pressurised air, sold as an 'air duster') to blow through the jets. Repeat the previous step and this one until you can see no more gunge.
To clean a carburetor without disassembling it, we can simply use a compressed air gun which is sometimes enough if the clogging is not severe. With the help of compressed air and fuel, most of the grease and fuel residues can be removed from the jets. Once done, carefully clean the upper tray and the float as well.
Sea Foam Spray delivers a high concentration of petroleum cleaning solvency and lubricity to carburetor throttle valves, intake runners and valves, and chamber areas.
Yes, you can spray carb cleaner, short for carburetor cleaner, inside the spark plug hole. This'll help dissolve hardened debris and loose materials in the spark plug wells.
Use carburetor cleaner to remove deposits, clogs & debris
Deposits inside the carburetor can clog fuel and air passages and reduce performance or stop the engine altogether. Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.
For that reason, we recommend on the container that soak times be limited to 15-30 minutes per dip with a total soak time not to exceed 4 hours for aluminum and aluminum-based parts. Generally, when soaked too long aluminum will darken but may also develop white spots.
Sea Foam helps lubricate the moving parts, particularly in the fuel system. Ethanol additives dry out the seals and leave a varnish that makes it harder for oil to lubricate the parts. Removing this varnish brings the engine back into top working order.
