There maybe an issue with fuel flow/delivery. Check the operation of the fuel tap and connecting hose. Has the fuel filter been serviced/replaced? Carburetor float level may not be set correctly, jets maybe dirty and blocked, these are all simple fixes if you are handy with some tools. Otherwise a relatively cheap fix by a dealer or more knowledge on the year/make/model of your scooter. Cheers.

Check the compression, pull the spark plugs one at a time if more then one. If you don't have a compression gauge, you can put your figure over the spark plug hole, be mindful that before it blows it's going to **** so make sure that you don't hurt yourself leave a little gap so your figure doesn't suction down to tight. If your getting compression it should **** and blow pretty hard. If it seems to have good pressure and suction. You might need to check your timing, also make sure that you can feel air moving out the exhaust, might not be able to with the pipes on it but if it won't start and your getting everything else it needs to run gas,spark, etc. It has to almost be timing or compression.

Take your spark plug out of the cylinder, reconnect it to the ht lead and place it on to your frame if you see a spark then your coil is fine, try a new spark plug, if there is no spark get a new coil and plug.

Remember there is a 2t and a 4t version of the kymco vitality and the spark plugs are different.

Snapper mower 331416kue won't start


Hello,

You can try buy a new spark plug and replace it with the old one.
I had the same problem!
You just have to keep pulling until it catches!
Or maybe it's the carburetor that needs to be replaced!
I had the same problem wih my scooter.
I just changed the carburetor and it worked fine :)

Scooter won't start with electric start or kick start.


  1. Try depressing the brake handle when starting.
  2. The battery has not been charged.
  3. The battery is hooked up wrong. This is often the reason for blown fuses.
  4. There isn't enough gas or two-stroke oil in the scooter.
  5. There is a gas flow problem, especially on the Euro Scooter or Yamaha models.
  6. The spark plug wire is not connected.
  7. A low battery or bad relay can cause the scooter to only start by using the kick starter.
  8. There is no spark to the spark plug. The coil is bad and needs to be replaced.
  9. Turn the key to the "on" position.
You need to check for a spark. There are a few ways to do this. The easiest way is to remove the spark plug and put it back in the spark plug cap. Then ground it to the engine - you should be able to lay it against a non-painted portion of the engine. Make sure there is good metal-to-metal contact. In a semi darkened area, attempt to start the scooter. You should see a definite spark at the tip of the spark plug. It's hard to see in direct light. If the color of the spark is blue, that means it's a strong spark. A white color is less strong, and a yellow color is weak. Most scooter starting systems are a bit weak (compared to cars). Even a yellow spark should start your scooter just fine.
The spark must occur at the right time. Just about all scooters made since around 1980 have an electronic ignition. These systems can rarely be set. In general, the spark occurs just before the piston reaches the top of it's stroke. There is a slight delay between the spark plug fire and the fuel-air mixture ignition. That's why the spark occurs a little early. Most ignition systems have an advance unit build in. As the engine speeds up, the time of the spark retards a little bit. This helps the engine fire the mixture at the proper time

There are a lot of tiny fuel and air passageways in the carburetor that must be kept clean it order for your scooter to run right. Carefully, take the carburetor apart. This can be relative easy (on a 50cc scooter). The carb has tiny passages that can get gummed up. Your scooter will not run correctly if the carburetor isn't completely clean, so take your time. I use a gallon container of carb dip (you can get a gallon at your local auto supply store).
First, remove all of the rubber and gaskets or they will get damaged. After a 20 minute soaking in carb dip, I blow out the carb with compressed air. You have to get all the jets and the passageways clean. Be sure the jets are clear, especially the starter jet. Sometimes carb cleaner won't clear out these tiny jets. Use a guitar or a piano string, a strand of copper electrical wire, or a tiny drill bit pin vise. Be sure not to increase the size of the hole in the starter jet or you'll change the tuning. Carefully reassemble everything, checking for cracks in the rubber carb boots and the gaskets. Replace them if they are old and cracked. Be sure and remove all rubber and gasket material first or they could get ruined. Spray carb cleaner also works if you're diligent.
If you have an electric choke, check it to make sure it works. Check the resistance between the wires - you should see around 10 ohms or less. Measure the length of the choke assembly. Remove the choke from the carb and plug the wires into a 12V source for 15 minutes. The choke body should be warm. Measure the length again - it should increase by around 1/8".
Next, consider whether your exhaust pipe is clogged. This is especially a problem with older two stroke scooters. The unburned fuel/oil mixture builds up in the exhaust pipe along with carbon over time. If the exhaust pipe is clogged, your scooter will run terribly or not at all. It can be difficult to tell if the exhaust pipe is clogged. The easiest way to tell is to remove it and try starting your scooter. It will be a bit loud - two strokes will sound like a chain saw. If it runs with the exhaust pipe off, you know that is the problem

hope this helps
