Hello, I’m a bit perplexed here by now, I have a scooter that doesn’t start any more. So I cleaned the carburettor, so it jumped on, but much too fat. I bought and installed a new carburettor, but it didn’t jump on again. I checked the ignition spark, no one is present. Cdi renews, nevertheless no ignition spark, no voltage on the ignition coil. I checked the side stand, there is no switch. In the meantime the battery was empty several times, mus s to be full that the scooter starts?
