Taizhou 150cc not starting

[gfscoot17]

Hey guys,
I've been reading these forums for a while but never posted. However, today my Taizhou 150CC scooter wouldnt start. I tried using some starting fluid down the air intake, the battery was fine (starter sounded good) but the scooter wouldnt turn over at all. I got a couple small pops with the starter fluid but thats it. Could also smell the fuel when it was cranking so im not sure thats the issue. Tried all different throttle settings but still nothing. The battery is now dying from me trying to start it so much. Kick starter hasn't worked since i bought it (the pedal slips on the nut its attached to, so it doesnt actually turn the bike, anyone know how to fix this?). I'm out of ideas other then to check the spark plug tomorrow, but I feel like that wouldnt cause it to randomly just not start. Help please!
Thanks a ton guys
