no start (no spark?)
 

As the op states. The engine cranks. I have good fuel and good compression. I started with new spark plug (gapped @ 0.28). I ohm checked sparkplug wire (good). Cleaned contacts on coil. Checked grounding. At this point no spark (with sparkplug in and out). I attempt to start 5x in a row then once it starts (I got spark?). Try gain and nothing. I check strator no visual evidence. I cleaned contacts on strator. Checked strator wire harness. No frays. 4 pin is tight. I have 2 wires. Black/red and Blue/Yellow. I have a Blue/white (with bullet style connector like the the other two) that I connected to the blue/yellow from strator. I don't see a mate for the black/red. Where does it go, can it be reason for not starting? With the description stating it cranks fine. I just have to do it 5x or more and maybe it will catch and I would use gas pedal to keep running. Once I let off and the procedure repeats. I looked at electrical schematics and some show the black/red going to cdi. The 4 pin has 3 wires. One going to the blue/yellow. The 2 pin has one (black) which it looks like it goes to main harness that connects to front of kart to key ignition. Thanks in advance!

what brand buggy you have? What is it?
