One of the most common issues is that the engine won’t start.

1. Remove the fuel cap and check for debris in the tank.
If there’s any dirt or debris, clean it out before proceeding.
2. Disconnect the fuel line from the carburetor and blow through it to clear any blockages.

If it still doesn’t start, move on to step 4.
