Find line from fuel tank to carb and remove from filter outlet. Squirt some gas into the line with a ketchup/mustard type bottle to refill carb. Add around 4 ounces of carb cleaner to the fuel tank.





Buy a "float-type" charger at Wal-Mart for around $20 to maintain the replacement battery.

What kind of scooter is it. Is it 6 or 12 volts? What do you mean by I continue to kick the Engine and will not turn over? If you Kick the engine crank and the engine does not rotate then it could be internal problem. Doubtful Check that the clutch is not too tight. This will cause the eng . not to rotate when you crack on it. It would be like cranking on the engine while holding the clutch engaged, wont crank. Next the engine needs three things for it to start. compression, fuel, and ignition or spark. check the simplest first. If the engine wont rotate no compression. If it rotates pull the spark plug out and check for it to be clean.check for spark. do not install spark plug to engine yet. connect the plug wire to it and ground it to the cylinder head with the ignition switch on and good charged battery crank the engine and you should see a spark jump at the end of the spark plug. Hold a finger over the spark plug hole on the engine and crank it . It should have some kind of pressure you can here. Then check to see if fuel is getting to the carburetor. Smell the fuel . It shouldn't smell like turpentine. If it dose then you need crab. Overhaul or cleaned out and the gas tank needs to be cleaned out. the fuel filter replaced. good luck
