Step 4. Remove the main and needle jet assembly, and take the idle jet off from the carburetor body.

NOTE: If any of the jets are worn or the buildup of contaminants is such that they can't be adequately cleaned, replace the jets. Even the smallest contaminants can clog a carburetor jet, so be very thorough when cleaning them.
