Why is my Cobra CHIP700L Chipper engine not running smoothly?

If your Cobra Chipper engine lacks power or isn't running smoothly, make sure the Throttle Lever is in the 'Run' position. Check if the air filter is clean; if dirty, replace it according to the engine manufacturer’s manual. Inspect the spark plug for fouling or cracks, replacing it if necessary. If it’s oily, remove it, cover the plug hole with a rag, and pull the recoil cord to clear oil from the cylinder, then clean and reinsert it. Ensure you're using fresh, clean unleaded petrol, replacing old petrol and using a fuel stabilizer for petrol stored longer than 30 days. Also, check the engine oil level and quality, adjusting or changing it as needed per the engine manufacturer’s instructions.
