No power My kymco agility starts, but bogs down when i give it throttle. It only has twenty miles on it. What could be the problem?

This seems to be a problem from your air intake (assuming it is 2 stroke) until the combustion chamber. If it has a valve system then it could be faulty. The valve has a small flap that flickers when petrol is thrown inside the combustion chamber. Basically when you open the throttle the engine tends to go to a higher revs, hence suction on petrol intake increases. What you have described means no petrol into the combustion chamber and hence tends to die out. So few things u need to check are:
1- Petrol flow to the carb
2- Carburator is blocked somewhere
3- Reed valve intake is damaged and hence you can see petrol popping out of the carb.

For now, I think this should be enough to help you, but please advise if it is a 4 stroke as then it could be different.

could be one of a few things. Most likely fuel related. 1) carb blocked main jet (whip it out n clean it) 2) air filter clogged up or split (remove spark plug and if it is black there is too much fuel and either the airfilter is blocked up or the choke is stuck on, if it is very white there is too much air getting infrom either a split air filter or leaking inlet pipe) 3) change spark plug.
