Hi, W32twood and the usual suspects are: 1. Throttle cables improperly adjusted, pinched or need lubrication. Idle adjusting screw needs to be backed off. Air fuel mixture adjusted too lean start with 2 full turns.
Intake system air leak. Fast idle choke ramp is not releasing.
Faulty automatic choke. Broken throttle return spring. Damaged diaphragm or slide.
Faulty MAP, TPS, ATS, O2, sensors or wiring/connector. Multiple carburetors not in sync.

If so, the first thing your going to want to check is the fuel system.
Theres a fuel hose running from the fuel tank to the carburetor. Remove the fuel line from the carb to check the condition of the fuel. Fresh gas has almost a clear look. If it appears to be fine, then proceed by checking the carb to see if there is fuel in the reservoir. At the bottom of the carburetor, there should be a small screw. Turn it out counterclockwise to see if gas comes out from one of the overflow fittings on the carb. If it begins to leak, then you most likely have enough fuel in the carb to start it.
If it comes out of the hose looking dark, or smelling kind of funny, then youll need to clean the fuel system. To do that, you must drain all of the old fuel, flush the fuel tank a bit with fresh fuel, refill it with fresh fuel, and also clean out the carburetor. If youve never done this before, i would reccommend having a technician do it for you. Lost parts or mis-adjusted carburetors can not only cause mechanical damage, but also be a potential safety hazzard due to performance problems. If the fuel looks and smells fresh, then your going to want to check for ignition next. Remove the spark plug from the cylinder head, attatch the boot to the top of the plug, make sure the electrode end is touching a good grounding point on the engine, and press the start button.
BE CAREFUL on this step. If the plug sint grounded well, it could lead to you getting an electrical shock from the ignition system. Its a good idea to hold the spark plug or boot with insulated pliers during this step, just as a precaution. While the engine is turning over, watch the gap on the spark plug end to see if there is a noticable spark. It should be fairly easy to hear as well. If there is spark, then your ignition system is most likely in good condition, so move on to the next step. If there is no spark, try this process over with a new spark plug.
If the new one still doesnt spark, there is a problem with one of the components in the electrical system, and that should be further diagnosed by a certified technician. I hope this helps you out a little bit. These are the first things that I would check. If you know the fuel system is in good condition, and you can see that there is a good ignition source, then you have a mechanical problem that would require more information to attemp to diagnose. If you have any questions, feel free to contact me. Ill be happy to further clarify or explain anything that I mentioned here.
Posted on Jul 28, 2009. Keeway scooters usually do not have kickstand switch. Check if there is one just in case.
If there is kickstand switch bypass it. Check fuel switch, fuel filter and hose. Try starting with no fuel cap. Check and replace spark plug. Check carburetor oil and oil tube. Check carburetor mixture and idle settings. The carburetor needle may be clogged in some case the carb must be disassembled to clean part or regulate needle height.
Unscrew the discharging fuel screw for the carburetor and check if there is fuel flow. If fuel flows test the ignition wiring, CDI and coils in the magneto. I do not have the service manual for this scooter. Check the service manual tests and diagnostics are the same and wiring diagram is similar. Ginko Oct 31, 2011. If you did not prep the bike for winter storage with Sta-Bil in your gas you might have some clogged carb problems You say this is a scooter but the description at top calls it a motorcycle. If it's a scoot then your engine and carb are underneath all that plastic your sittin' on.If it's a motorcycle your carb is right behind the engine between ur legs.

It has a rubber gas line connected to it. Get some starter fluid from your local auto parts store and spray a short burst into the air cleaner and then hit the starter button. It should start but if it won't sit there and idle youv'e got a plugged card idle jet.time for a mechanic.next year prep the bike and disconnect the battery and you won't have to buy a new one.Good Luck!!
