Kymco zx 50

I possibly have the same problem. I have narrowed it down to a fuel (lack of) problem. If you remove the seat and take off the vacum tube leading to the fuel tank cut off valve ( on the bottom of the fuel tank) you will be able to squirt a little fuel directly into the intake manifold,replace the tube and hopefully it will start instantly.no dought it will then stop repeat the process several times.
I suspect there is an electric soleniod system to deliver fuel on startup, I have dismantled the carb and am fairly sure the problem is with the electric needle system on the rear of the carb.
Hope it helps

CHECK YOU HAVE A GOOD EARTH TO THE COIL AND CHECK THE PLUG?

Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? If needed, add water to the battery cells enough to cover the top of the cell plates.Try a jump start from your car battery. Is the kill switch on? Check the operation of the ignition switch with a volt ohmmeter. You should be getting power into and out of the ignition switch.

If the bike doesn't start and run properly check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Broken or out of adjustment, it would kill the spark. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.

Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing.
