i think im just going to buy a new engine. Another problem i am having, is that i tried to take the engine apart and sine i could not get the fly wheel off, i went to put the engine back together, and you know that gear that is at the front of the engine, the gear that connects to the spur gear to make the car move, well it wont tighten down on the shaft thats in the engine. It spins freely, and i dont think that is right because if it spins freely then when the engine shaft turns, the car wont move. Is this correct? Isnt it suppose to be tight? the fly wheel is tight to the shaft so im figuring its suppose to be tight
