An attachment for purging the inside of the carburetors which is comprised by a tubular device having a carburetor connecting member and quick connect receiver extension. The attachment is connected through the bottom of the carburetor or through the feed fuel line of the carburetor. The attachment is attachable to a quick disconnect fitting which can be connected to a conventional car tire air nozzle or pressurized can with the same fitting as the car tire nozzle. The attachment allows all the jets and passages located on the inside of carburetor to be purged at the same time with multiple short blasts of compressed air or pressurized can solvent but without the carburetor being removed from the engine or taken a part. The same principles can easily be applied to all type carburetors for either a two or four-stroke engine.
