2 stroke help

I've got myself a new 2 stroke motor and I'm currently trying to install it. I've run in to a few problems though. There is a small wire coming out of the same place that the spark plug wire does and I have no idea what it's for. Also, I apparently don't understand how to hook up the fuel lines to the carb. And while I'm talking about the carb the motor I took off didn't seem to have one? It just had a small throttle body looking thing. So now I have no idea what is suppose to go where.
I found a stock picture of my motor on amazon.

That's what I'm working with. Any assistance would be appreciated.

So the carb just has the one fuel line hookup? The butterfly from my old motor had two. Here I was thinking this would be as simple as "take old motor off put new motor on, hook everything back up". *sigh*

Alright, thanks. So, if the gas goes straight from the tank to the carb to cylinder, how do you control the throttle speed on the motor?

I can't seem to get this motor of mine running. I've got it mounted to the scooter but, It won't start. Won't even try. I've got my fuel mixed, opened the choke all the way, and the spark plug is in.
Only thing I can think of is maybe the gas tank needs to be higher than the motor because there is no fuel pump? Anyone have any ideas?
