Ok sorry it has taken me awhile, I replaced the battery with a new one this weekend, I pulled what I believe is the CDI. It has 4 plug ins on 1 end and that is all.On the side it says GY6125 2007 08 12VAT. I tried to start it after I replaced the battery but still nothing. I checked for a spark again but could not see one this time.

I was taking off what I think ws the CDI,( Is the CDI the unit where the spark plug wire goes into)?, if so when I was taking it off the plug wire came out of it and there were no braided strands on it so I cut the sheath back to expose wire and put it back into the boot ( on the unit not the spark plug end ) and then checked for spark and it was sparking like crazy. I tried to start it but no luck, I tried adjusting the air/fuel mixture screw and the idle screw but no luck. Any suggestions? what settings should I have the adjusting screws to? It does have a new plug and I do smell gas?

I am not sure if this is the CDI or the Stator. where is the cdi located at? I have 4 wires going into this and by looking at another post and the pics he put on, the part I have looks like one of his pics other than the cover over the connectors is black and not white.
CDIs look like this:
