my taotao 125 has no spark, I have changed the coil, cdi box, the kill switch, the key switch & the stator pu, & the voltage reg, & the batt, the only thing not replaced is the starter soliniod I have used my ohm meter on the wiring & everything checked out good, all good pig tails & ground, no loose pins, what can be the problem? thank you for your help. Frank.
