Changing Spark Plugs
- Remove spark plug by disconnecting the spark plug lead and removing the plug using a spark plug socket.
- Clean any deposits from the plug with a wire brush or spray-on plug cleaner.
- Inspect the plug for heavy deposits, cracked porcelain, or burned away electrodes. If any of these exists, replace the spark plug.
- Use a spark plug gauge to measure the gap between the two electrodes at the tip of your spark plug. (Many small engines require a .030″ gap. Check for the specifications for your model)
- If necessary, use a spark plug gauge to adjust the gap by gently bending the curved electrode. When the gap is correct, the gauge will drag slightly as you pull it through the gap.
- Reinstall the plug, taking care not to over-tighten (15 ft. lbs. MAXIMUM ). Then, attach the spark plug lead.
Air Filter Upgrade Instructions

- Remove and discard the original cover (B), filter (C), filter cup (if equipped), base (D), and gasket (E).

Cleaning & Adjusting Small Engine Carburetors
