Need replacement handlebars and throttle

hi how do I rewire the throttle

The throttle broke on my scooter first off

We need a right-hand throttle and grip for model H1-EGE. Do you have one in stock?

Where do I get a replacement please let me know

On the handlebar in the thread where I screw the trotting it doesn't screw in the thread is all stripped out so the throttle grip can't be screwed in with only the power comes on

First of all I wish I can ask everyone that is having the same problem as me with this scooter,, how do you know it has something to do with the throttle? Did it quit running? Not moving? Everything works OK except it just won't move when I press the switch to go. I don't know what's going on.
