If you need to find out info on the engine .
your best bet is to have a look at the side of the housings (motor) it should say either 12a or 13b and that is your engine. the difference between a 12a and a 13b is not really that much, basically the 13b is about 20 millimeters wider. witch gives it more displacement. round it up to 1.2 liter or 1.3 liter respectively . have fun man
