If your battery is low or dead, the pistons can’t compress the fuel enough to create an explosion that generates enough energy to restore enough power to the battery to repeat the process.įailure to explode compressed fuel is a different matter, related to sparking rather than compression. If your engine is sputtering but refusing to turn on fully, your battery may be low or dead. If your engine is failing to compress fuel and you are using an electric starter, there will be a few symptoms that might point you in the direction of an electrical failure rather than a true compression failure, though. Unfortunately, problems with the compressor tend to be expensive to fix, and there’s little you can do yourself. If this happens, wait a few hours before starting again.Īfter all, it’s the site of constant small explosions that are used to power your scooter. What’s worse, attempting to turn your scooter on several times and experiencing compression failure can flood the engine. Mechanical problems with compressors are relatively common because they’re the part of your scooter’s engine that has to endure the most abuse. If your engine isn’t starting up but it’s making noises, it isn’t compressing fuel effectively. Compressionīefore fuel can explode and provide enough power to keep the engine running, it needs to be compressed mechanically by a piston using electrical power from the battery. Now that we’re familiar with the way that things should work let’s look at where there might be problems that would prevent the process from becoming self-sustaining. The process repeats and the engine is on.The force of the piston being pushed backwards powers a resisting sprocket which restores more power to the battery than was used in the first compression.The explosion of the fuel pushes the piston backward.The spark plug sparks, causing the fuel to explode.

The fuel is compressed by the pistons of the engine, still using battery power.

Electricity from the battery powers the starter, which powers the compressor to allow it to begin compressing fuel.

Fuel enters the compressor in each of the engine’s chambers and fills them.

Fuel rushes out of the gas tank into the compressor.

The starting process goes something like this: Let’s go into more detail regarding the starting process so that you’ll be able to identify points of failure. You also need to make sure that the scooter has gas and that the battery isn’t drained, of course. So, to get your scooter to start with an electric starter, the following components need to work in harmony: Pressing the starter button completes a circuit between the battery and the spark plug and also a circuit between the battery and the compressor, and turning the ignition opens the fuel valve. Your actions each affect a different component of the scooter, though.ĭisabling the engine kill switch removes a physical barrier to forming compression within the engine. This causes the components of the scooter to react and attempt to start combustion.

Your input is to turn the ignition, to disable the engine kill switch, and to press the starter button. It’s important that you understand that your scooter’s engine has two different states: successful perpetuating combustion, and being off.įor your scooter to start successfully with an electric starter, your scooter needs to activate the components in the right order after receiving the correct input from you. The scooter’s components have to work together in harmony to both start and then to sustain the starting reaction to run. In this article, we’ll go over why your scooter might not be starting and give you a few tricks regarding what to do before taking it into the shop. If your gas-powered scooter isn’t starting using an electric starter, you’re probably desperate to find a solution which doesn’t involve taking your scooter to the shop or making expensive repairs.
