Replace coil
Because the ignition system consists of a lot more parts than just the coil. check the distributor and plug wires. make sure the coil is hooked up right. if you changed the coil, and it didn't fix it, the coil probably wasn't the problem.

Misfire Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
To fix a no-spark issue on your mini 4-wheeler, first check the spark plug for wear or damage, and replace it if necessary. Next, inspect the ignition system, including the ignition coil and wires, for any faults or loose connections. Ensure the kill switch and any safety features are functioning properly, as they can prevent spark. If these steps don’t resolve the issue, consider testing the battery and electrical connections for any faults.
Replace the coil.
