Answer 1

Everything Guard just said sound bang on to me.

Simple note to take, and so many people get this simple point wrong.

Make sure you tighten the wheel back in straight. You see little "check" markers on the swing arm, these will guide you. Pocket bike or not, no harm getting a measuring guide out to tdouble check.

Answer 2

Remove the carburetor, disassemble and clean it with carburetor cleaner (available at auto parts and motorcycle shops).

There's probably some dirt in the float seat preventing the float needle from stopping the fuel entering the float bowl.

Without knowing the year, make and model # of your bike, I can only suggest that you loosen the rear axle and pull the rear wheel back to tighten the chain.
