2. Remove the seals from the throttle valve.
Note: Cleaning agents may damage the seals, so they must be removed from the throttle body.
3. Manually open the throttle valve fully.
Note: Do not spray cleaning agents on the outside of the cylinders, inside the spring housing or on the connector.
4. Spray carburetor cleaner into the air hole of the throttle body to dissolve all traces of dirt.
