2. Remove the air cleaner/cover to access the carburetor throat.
3. Use a scissors to cut the Cleaning Tube to a straight length of 6 to 8 inches.
4. With the vehicle in park and parking brake applied, use a helper to start and hold the engine at 1000 RPM over factory idle spec for the duration of the spray treatment.
5. With tube attached, spray continuously until contents are empty. (Approx. 4 to 5 minutes.)
6. When can is empty, shut off the engine and allow the engine to hot soak for 5 to 15 minutes.
7. While waiting, re-attach and secure air cleaner/cover.
8. After hot soak period, start and drive the vehicle under load for at least 5 minutes.
