Hi, let me start by saying I just joined this forum, wow....this is great wish I had heard about it sooner!.....I'm hoping someone out there can help me, my son has a 50cc Gio ATV and I'm having some issues with it, sometimes I have spark, sometimes I don't, and it's weird because I could be rolling it over and there's nothing,then all of a sudden there is then it's gone.I'm confused not sure where to go from here ??....any ideas or help from anyone would be greatly appriciated.
