Hey guys. I have this Chinese pentora that Sparks then doesn't spark. I've replaced cdi box. Stator. And coil. this thing has drove me crazy. Please help.
also the quad is new.

 

First thing to change is the spark plug. If that doesn't work do the tests in the "help diagnose stator" sticky at the top of the engines section here. Do not assume the ohms and voltages listed there are holy writ, but give some indication of about what you should be getting. If something is way out, you have probably found the fault. The ignition and kill switches can be the cause of intemittent problems. If it is AC ignition and you can catch it with the fault on, check the kill wire is not earthed when the switches are on run.

 

First thing I did was put a new ngk in it before I did anything.but thanks for the info.
