First off thanks for any and all help that might be given. Very new to this and don't have a good direction except for what I read on here so here it is. Bought a new Coolster 125 last Xmas for my daughter and ran fine till summer. Slowly went down hill problems with foot brake light (fixed), key switch (replaced and fixed) and finally the stumble problem. It will just start to do it at anytime till it dies. Acted like the choke was still on but it wasn't, tried different gas, bought a new carb, new performance CDI box. Any Ideas or answers? Thanks
