The button to start the horseless carriage on Time Tangled Island is on the rear. Push it and the car will drive across to the right. You can climb the tree to the roof, where the Sun Stone piece is in the second chimney.
At the Edison house (9 o'clock, 1877 AD). The horseless carriage at far left will start up if you press the button on back. This will let you reach the tree, and then the roof.
It is in one of the chimneys on top of Thomas Edison's house (9 o'clock, 1877 AD). To reach it, start the "horseless carriage" at far left and ride it across to the tree.

There are five different "machines" to start, on four separate Poptropica islands. * On "24 Carrot Island", the machinery in the Carrot Cake Factory is restarted with the power switches : the middle one all the way down and the other two halfway down. * On "Time Tangled Island", an early horseless carriage is started by pressing the starter in the rear. * On "Big Nate Island", a jet-ski is started with a key. * On "Astro Knights Island", the hovercraft is activated using manure, and the flying saucer Excalibur is fueled by a fuel rod from the imprisoned robot invader. (see related answers, which specify a particular island)
The Aztecs (5 o'clock 1519 AD) are missing a piece of the Sun Stone. It is in one of the chimneys at Thomas Edison's house (9 o'clock, 1877 AD). Go left to the horseless carriage and start it, and ride it to the tree, to reach the roof. The stone is in the second chimney. Return it to the rulers at the Aztec pyramid in 1519 AD.
Thomas Edison's workshop is at 9 o'clock on the time device, 1877 AD. He needs his phonograph (in Ancient Greece, 1 o'clock, 328 BC).

On Edison's roof is the Sun Stone piece (Aztecs, 5 o'clock, 1519 AD)
