2) Clogged fuel line: A clogged or damaged fuel line can prevent fuel from flowing freely to the engine. Check the fuel line for any obstructions or cracks.
3) Bad fuel pump: A bad fuel pump can't deliver enough fuel to the engine. Test the fuel pump by disconnecting the fuel line from the carburetor and turning on the ignition. If the fuel doesn't flow freely from the line, the pump is likely bad and needs to be replaced.
4) Bad carburetor: A dirty or malfunctioning carburetor can prevent fuel from entering the engine. Remove and clean the carburetor or replace it with a new one.
5) Bad spark plug: A bad spark plug can cause the engine to misfire, which will prevent it from getting enough fuel. Remove the spark plug and check its condition. If it's worn or damaged, replace it.
