Cleaning a Carburetor
Sludge and other debris can clog the carburetor of a 2-stroke motor, so maintenance is a top priority. To clean a carburetor, start by removing the part from the machine. Spray the carburetor with specially made cleaner that will remove rust, sludge, and debris. Be thorough; there are plenty of valves and crevices in a carburetor that need to be cleaned out.
Once the cleaner has been applied, wipe the carburetor down with a clean cloth. With an air compressor, blow out any remaining debris. Once again, wipe off the carburetor and then reattach it to the motor. While working on the motor, be sure to check the oil level and add Mercury 2 cycle oil if need be.
