It will turn over but wont crank

Not starting issues are usually spark or fuel problems. If you have gas getting to the carb then check your spark. First check all the wire connectors and plug wire to make sure everything is connected. If you find a loose connection fix it then try it. If not, then remove the spark plug but leave it attached to the plug wire set it on the cylinder head and turn the engine over. You should see a bright spark. If you have a really weak spark or none at all, then it may be your ignition coil or a related ignition part.
