Hi have a Linhai 300cc quad 4x4 (2011) Not running at the moment , Cranking over and not spark , I've removed spark plug and tested it against engine block getting two sparks when you turn on ignition only , And no spark when cranking engine over I've tested the coil and lead, Cdi and kill switch, stator, all seem good, anyone with any ideas ?

 

Just been answering a query about Linhai ignition, different model but that spark when you switch on would indicate a Kawasaki 300 style "ignitor" ignition rather than CDI, same as the other Linhai

If your wiring is like this, note pos wire from ignition switch to coil and ignitor, then your ignition is the same as most 1980s cars, 12v coil and signal from trigger coil fed through "black box" to give a negative pulse at the right time, to the coil.
