1: Carb is kit stock ?

2: Have you jetted it for your elevation ?

3: Idle Screw - have you adjusted this?

edit: heres a wiki link re: carb & elevation : Carburetor - Wikipedia, the free encyclopedia ( this will take u right to your point of interest )

Try adjusting the fuel/air mixture screw, or the idle screw, that may help. If you said that there is oil coming out of the exhaust, it could be the PCV system (hose from crankcase of 4 stroke engine into carb). Check your oil, is their gas in the oil, or is the oil level low? Your problem could be caused by many things.
 
^ great point - might be excessive blow by

edit: good catch, im building a 2smoker and am in that mindset /thumbsup

Deadend: My bike is also a chinese 2 stroke, but I fix just about anything with a motor: cars, lawnmowers, tractors, etc. My tractor had oil coming from the exhaust, and would not run consitantly so I took the carb off cleaned it, drained the oil(gas was in it from flooding) and then re-adjusted the carb and now it runs great. Your problem mick29 could be as simple as that.
