I have a Suzuki AP 50 moped. I got a new engine and spark plug. It has compression but won’t start?

The battery is charged too

or:The battery is charged too

or:Internal combustion engines require a fuel/air mixture and an ignition of such (and a method of exhausting the waste). Assuming the exhaust isn't clogged I would first pull the spark plug wire and remove the spark plug. First ensure the bottom of the spark plug (ground strap and ground electrode) that was inside the engine isn't wet. If it is then you are experiencing a \"flooding\" situation meaning the fuel/air mix has too much fuel and too little air. It could also mean that your spark plug is not receiving the electricity necessary to spark and after repeated attempts to start the engine has resulted in too much fuel in the cylinder. If you replace the spark plug wire onto the connector (top of spark plug) and let the spark plug hang from the wire or rest on the engine, anyway it fits and you can still see the bottom of the spark plug, attempt to start the engine and watch for spark to jump from the electrode to the ground strap (bottom of spark plug). If there is spark install the spark plug into the engine again and attach the spark plug wire. If the engine has a manual choke adjust the fuel/air mixture to have more air. Attempt to start the engine again. If still unsuccessful you will need to double check that you have the correct spark plug for the engine. If so, then you will need to find the correct gap for the spark plug ground strap and make sure you have the correct gap on your spark plug.All this is assuming the gasoline is recent and hasn't been sitting for a long period of time. Another thing you could do while you have the spark plug out of the engine is to use a flashlight to see into the spark plug receiver opening and watch for a mist of fuel/air to spray into the cylinder when attempting to start the engine. If the fuel isn't getting to the cylinder it could be many things: fuel line blockage, faulty choke, gummed up carburetor (or bad injector if fuel injected), and I must mention to cover the bases no fuel in the gas tank.
