KYMCO Sputters and Dies at random

I bought a 2009 Kymco People 150 about 10 months ago brand new from the dealership. it has about 2500km on it and all of a sudden last month it started sputtering when it was at full throttle going about 55 mph. about a week after that episode, the scooter died as I was driving at about 20 mph, I thought that I had run out of gas as I was very low. I walked to the gas station and bought some gas and filled it back up in the dark. Unfortunately I also spilled gas all over the scooter as well. Now the scooter will die at random, sometimes it will die after 100 yrds after sitting for 5 hours, sometimes it will die after 2 miles, sometimes it wont die at all. The last time it died I was going about 35 mph after driving it for about 4 miles, as it was sputtering on the road I listened very carefully and it sounded like a very loud "clicking" or popping was come from somewhere in the engine (almost like the engine was coughing.) and then it died. 5 minutes later I was able to start it up and drive it 4 miles home. Another useful piece of info is that usually when I fill up the scooter I will fill it up pretty full, I have heard that that is not a good thing to do, does anyone have any advice or know what it might be?

Filling the tank full is okay. The problem sounds like condensation in the gas tank has made it to the carburetor. There should be a screw or drain plug on the side or bottom of the carb float bowl. Drain the carb and also drain some gas from the fuel line to remove any water and trash in the system. Chances are this will get you back on the road.

I just purchased a 2007 Kymco People 150. The previous owner received it as a retirement gift from his employer. He never had it licensed or even ran it at all. I mean nothing!!!!. He just put it in his garage, then his basement. It has 2.3 miles on it. He claims it is just from pushing it around to different storage places.
First thing I did was purchase a new battery (120 cca). put it in, added 92 octane gas and cranked it over. It took a few tries, but it started within a minute, but immediately died. I again tried to start it with the same result. It just starts, runs for about two seconds and dies. There is no problem getting it started, but will not stay running.
I took the carb off, cleaned all the jets, ports, ect... as best I could without getting way too far into it.
Put it back on, same thing!
Is there something I missed by not going too far into the carb or could this be another issue that I need to look into.
Any help would be appreciated.

    Make sure the needle valve on the float is working properly. I tore into one i think there is a factory defect there.

SOURCE: 2007 kymco agility 125cc scooter

could be one of a few things. Most likely fuel related. 1) carb blocked main jet (whip it out n clean it) 2) air filter clogged up or split (remove spark plug and if it is black there is too much fuel and either the airfilter is blocked up or the choke is stuck on, if it is very white there is too much air getting infrom either a split air filter or leaking inlet pipe) 3) change spark plug.

You don't have to be tech savvy to troubleshoot the coil.
You'll need a multi-meter that reads resistance; which is measured in Ohms. Borrow one or buy one at Radio Shack, they're inexpensive.
You'll also need to know the primary and secondary resistance values of the coil; which is usually found in a repair manual- perhaps even in your owner's manual.
If you have neither, call the scooter dealer, make sure you tell him the year, make, and model of your scooter and that you need the primary and secondary resistance values to the coil on your scooter.
Once you have the multi-meter and the specs to the coil; it's time to set up and run some tests.
Locate the coil on your scooter- follow the two leads that come out of the coil until you come to the plastic connector. Disconnect the connector.
With your multi-meter set up to read resistance- take a reading across the two coil wires; if the reading is within the manufacturer's specs (plus or minus 20 %) the primary side is okay.

To check the secondary side of the coil, leave one of the tester's probe attached to one of the coil's wire; detach the spark plug wire from the spark plug and attach the other tester's probe into the spark plug wire's terminal's end; and read the meter; if it is within (again, plus or minus 20%) of the manuals specs, the secondary side of the coil is good.

Therefore the source of the problem is NOT the coil.

Jiggling the kill switch? Are you referring to checking for loose or damaged connections?

Other possibilities; worn or melted wire grounding out at the switch- bad stator; rectifier, or CDI box. How tech savvy are you and mechanically inclined? Because you will need a repair manual to guide you through the troubleshooting process.

Unless you know how to read schematics and use your multi-meter- it could become an involved process- you may just want to bring it in for servicing to the dealer
