2001 KX 85 Small Wheel

[Wild]

Hello,

I bought a 2001 KX 85 Small wheel about 3 weeks ago. It ran fine for 2 weeks fine but when i was out on it one day i gave it a little thrash to see what it could do. Then once i calmed down the bike started to die like running out of fuel. So i tried to kick it but it wouldn't start. So i checked the fuel was on and looked in the tank it was half full. So i pushed it round the corner to one of my mates and he had a look. We tried to bump start it a few times still no luck. So a few days ago i tried to start it again with a bit of luck. I put on the choke kicked it and held it full throttle. It started but when i let the throttle of a little it died. So i cleaned the carburettor today and still no luck.

So I'm asking if any of you may know what the problem is?
