I think the float on my kids 50 cc is sticking...its not getting enough fuel it seems. I'm going to take it apart tomorrow to clean it. Should I also check the float height? what should it be and how do i check it? Its a kazuma. thanks!

 

could be dirty jets.......so clean them while you got it apart along with the needle seat! good luck.

 

I agree, jets.
I've not heard of the needle sticking closed.

 

I have not put a good battery in yet. Could a dead battery make it stall and bog down after awhile?

 

Is it a two stroke? If so here is a easy to use trouble shooting guide.
