Hi , I'm stuck on a situation we have a chinese 110cc atv it won't start without being jumped with a jump box i tried to start it wthout the jump box and nothing. I got a new battery,new carb.,changed oil ,new spark plug,but when it's start it stay started but i don't want to have jump all the time,so please can some body help me and asked a few people and they said it can be a cdi box,silinoid, idk please help. it runs and goes but when it starts it will try to take off and the brake barely stops it ?

You sure the battery is good?

Go ahead and replace the cdi, coil, sylinoid see what that does.

Adjust idle lower so it won't move fwd when you start it. The brakes should be adjusted so you can stop it easily with front drums and rear disk.
