I just bought this quad. It needs some work, but I'd like to get it running nice so I can ride it with my kids. It smokes a lot....mabey rings we're thinking? And this is wierd: To start it, you have to pull start first then warm it up, then the push button will work. If you dont pull start it, you can push the button forever and it wont start. The batteries new, its gettting spark...i dont get it, I could see the other way around....Any ideas? Also suggestions on where to get parts?

 

Probably low on compression, when you pull start it you spin it faster than the starter does, after its warm the starter must spin it fast enough.
