What if the scooter will not start?

With the onset of cold weather, the owners of motor vehicles are increasing problems with starting the engine. No matter how simple the device was, but immediately to determine why not start the scooter pretty hard. Let's find out the causes of this “whim” and find methods to eliminate them.

Not going to discuss in detail the General structure of the scooter will start immediately with the motor. We all know that for the operation of the internal combustion engine needs three components: spark, fuel and cylinder compression. And as in the technique miracles do not happen, it should start with a check of exactly these three elements. This so-called "typical" problems.

Why not start the scooter, a stepwise diagnostics

1. Ignition system. Diagnosis begins with checking the plugs. It should Unscrew and inspect the condition of the electrodes. The presence of reflow or damage to the insulator clearly indicates the need to replace candles. Often, when the inspection electrode is detected residue. It also can cause the loss of spark. Nagar it is recommended to carefully remove the contacts with emery cloth-‘my best" and check the electrode gap.

The Reason for the disappearance of the spark can also be “Bay” candles. If when removing the part, it was wet, it should be dried well and put it back in the cap. Then you need to check for spark. To do this, the scooter turn the ignition candle electrode or the lower threaded part attached to the cylinder and run the crankshaft. If between the electrodes a spark – a serviceable item.

2. The power supply system. Spark but will not start the scooter? Check the fuel supply. There may be two reasons: either it is not served at all, pleasure is served in abundance. Diagnosis should start with the gas tank, gradually passing across the food system. If the fuel tap and fuel lines clean, then proceed to the carb. It is necessary to carefully remove, disassemble and rinse thoroughly.
One comment! Never attempt to blow out metering jets carburetor mouth. The slightest drop of moisture will create more problems than dirt!

3. Compression. If the electrical works and power system for Troubleshooting problems not identified but still will not start the scooter, what to do next? It is now followed by the check piston. If it works, the motion of the piston to the top dead point in the cylinder. must be created a certain pressure. You can check special compression gauge. If the indicators on the instrument below the parameters set for your engine type, you need to replace the compression rings. And this is a complete engine overhaul.

Will Not start scooter: nonstandard reasons

Modern scooters can be triggered with buttons, and with the kickstarter (with the “legs”). Found this situation that the engine of the first method fails to start and the second start with a half-turn. In this case you should check the main fuse. It is located in the battery compartment. Most often the faulty fuse takes over the voltage, and the battery power is not enough to start engine. The fuse must be replaced.

The Second non-reason won't start the scooter, it can be old fuel in the tank. The quality of our gasoline needless to say. Try to drain the remaining fuel tank and replace it with a new one.

One more tip in closing: if you are in doubt about their ability to independently understand the causes of the problem, don't risk it. Not everything is learned in practice! It is better to consult the experts. Because the cause of the engine failure could be the failure of the factory adjustments.
