1. Incorrect Fuel Mixture:
- Incorrect fuel-to-oil mixing ratio can cause the plug to foul quickly. Make sure you're using the recommended ratio for your Blaster.
- Check if you're using the correct type of oil specifically designed for two-stroke engines.
2. Engine Over-Oiling:
- Excessive oil can cause the plug to become fouled with unburned oil and carbon deposits. Check if there's oil leaking into the combustion chamber.
3. Choke Issues:
- If the choke is left on accidentally or the float needle valve in the carburetor is not sealing properly, it can lead to over-fueling and fouling.
4. Air Filter:
- A dirty or clogged air filter restricts proper airflow, causing incomplete combustion and plug fouling. Ensure your air filter is clean.
5. Ignition System:
- Check if the spark plug is properly seated. A loose spark plug can lead to improper combustion, causing fouling.
- Confirm that you're using the correct heat range spark plug for your engine. If the plug is too cold, it might foul more easily.
6. Piston Ring Issues:
- Worn or damaged piston rings can allow oil to pass into the combustion chamber, causing fouling.
7. Crankcase Seals:
- Leaking crankcase seals can allow oil to enter the combustion chamber.
If you've checked all these potential issues and the plug still fouls in two days, it's recommended to seek assistance from a professional mechanic or a knowledgeable two-stroke enthusiast who can further investigate and diagnose the exact cause of the fouling.
