Lightbulb Diana Scooter problem

hello, I am new in this forum. I have a 2 strokes scooter and I have the same problem with my scooter. It runs wells in downhills or even plane roads but once it reaches up hills it shouts down. I cleaned the carb already, and I have a new battery, so I cannot figure out if it is an engine problem?? Also my scooter produces lot of smoke when running does anyone knows why it is doing that and how to solve this problem?? It also backfires when starting up. Please if someone had had any problem like this and have some advice it will really help me.
Thank you for your help!!!

You could try a new spark plug, but the usual cause of black smoke is a rich fuel setting. You say that you cleaned the carb. Did you disassemble it and clear all passages and then rebuild it to factory settings?
