i'd go back to the beginning, and start with the basics.
you know you've got spark. make sure it's dry and gapped at .025-.030.
you say the plug was wet so you have fuel. undo the fuel line at the carb and turn on the petcock and make sure fuel's coming out.
hook the fuel line back up, turn on the petcock, and see if your carb fills up. undo the float bowl drain screw on the outside and see if fuel trickles out.
if so, fuel's good. if not, fuel's clogging.
with the air filter off, look into the throat of the carb, twist your throttle, and make sure the slide raises up all the way. also, make sure when you start twisting it, that the slide moves at all. if not, adjust the barrel that the cable goes into at the cap on top of the carb till it does.
now, screw the idle adjust out 3.5 turns. look back inside the carb and screw it in some more to make sure it's raising the slide a tiny bit. then unscrew slowly till it doesn't lower anymore. ideally, you want to find the spot where the slide just starts to move up.
assuming fuel and carb's all good, check your wiring. i don't know which colors you have, but someone here does, i'm sure. make sure all connections are tight. i'd leave the kill switch disconnected and taped up so it doesn't short out until you get it running. also, make sure your plug wire is screwed into the CDI box all the way. it looks sealed, but it's actually just twisted onto a screw inside the box. twist it clockwise to make sure it's tight. don't overdo it. also, make sure it fits tight on the plug itself. with the stock wire, you know you have to unscrew the little nipple off the plug, right? should be just threads on the end of the plug.
so we have spark, fuel, and wires.
it's clutch time.
push your bike forward without pulling the clutch lever and make sure the wheel skids. now pull the lever, and make sure it doesn't. it's more or less that simple. if the wheel moves without pulling in the lever, you need to adjust the cable looser.
the basics are now covered.
pull the choke lever up, push the tickler a couple of times, pull in the clutch and pedal away. dump the lever, don't just let it out, and keep pedaling, and give it some throttle. if it doesn't start the first time, try again. and again.
if it kinda starts, then dies, try half choke.
if it's still trying, screw the idle adjustment in another half a turn, this'll give it more throttle.
when you're starting it, always keep pedaling. my bike sometimes takes 15 feet of hard pedaling, and sometimes starts with a nudge
now, if it starts, pull the clutch lever in and keep revving the throttle. if it's revving really high, unscrew the idle adjuster a little till it sounds good.
if it's still revving high, your throttle cable's too tight.
(edit) if it starts, remember you don't have a kill switch. hit the brakes and dump the clutch to kill it.)
if none of this works for you, send it back.
