How to Care for a 2 Stroke Engine

2 stroke engines are found in a variety of equipment, including motorcycles, snowmobiles, weed whackers, and chainsaws. They are known for their simplicity, power, and relatively low cost. However, they also require more maintenance than 4 stroke engines. By following a few simple steps, you can keep your 2 stroke engine running smoothly for years to come.

1. Use the Right Fuel

2 stroke engines require a mixture of gasoline and oil. The ratio of gasoline to oil will vary depending on the engine, so it is important to consult your owner’s manual for the correct ratio. Using too much oil can cause the engine to smoke and foul the spark plugs. Using too little oil can cause the engine to seize up.

2. Change the Oil Regularly

The oil in a 2 stroke engine is responsible for lubricating the moving parts and preventing them from overheating. It is important to change the oil regularly to keep it clean and free of contaminants. The frequency of oil changes will vary depending on the engine, but most manufacturers recommend changing the oil every 50 hours of operation.

3. Clean the Spark Plugs

Spark plugs are responsible for igniting the air/fuel mixture in the engine. They can become fouled over time with carbon deposits, which can prevent them from sparking properly. It is important to clean the spark plugs regularly to keep the engine running smoothly. The frequency of spark plug cleaning will vary depending on the engine, but most manufacturers recommend cleaning the spark plugs every 100 hours of operation.

4. Check the Air Filter

The air filter is responsible for keeping dirt and debris out of the engine. A dirty air filter can restrict airflow to the engine, which can cause it to run poorly. It is important to check the air filter regularly and replace it when it becomes dirty. The frequency of air filter replacement will vary depending on the engine and the operating conditions.

5. Store the Engine Properly

When you are not using your 2 stroke engine, it is important to store it properly to prevent damage. The following steps will help you store your engine properly:

1. Drain the fuel from the engine.
2. Remove the spark plugs and pour a small amount of oil into the cylinders.
3. Pull the starter cord several times to distribute the oil.
4. Replace the spark plugs.
5. Store the engine in a clean, dry place.

By following these simple steps, you can keep your 2 stroke engine running smoothly for years to come.
