Hello, I have a scooter of the brand Keeway for about a year. It is the model F-Act 50. Towards the end of last year he sometimes stuttered after the start at the start of the ride. However, that has settled after a few meters. Besides, he sometimes did not jump on. Now he does not start after the winter at all. Neither with electric- nor with kickstarter. However, if I remove the air filter and spray brake cleaners it runs. Even if I then without brakereini Every now and then it runs round, but otherwise it’s not possible. So it just doesn’t start “cold”. Since I’ve dealt with two-stroke technology little so far, I have a few questions: Is the e-choke also active if I “antrete” the scooter? I have already expanded it and hung it on 12V, it moves out slowly. That seems normal, but I don’t understand why it has to go so slowly. However, if I get to the plug of the choke fair ic h no voltage. I don’t know when and how much voltage has to arrive. I also checked the ignition and put the carburetor in an ultrasonic bath. But it didn’t look really dirty. I also “tested” the low pressure gasoline pump by pulling the vacuum hose. Thereupon, petrol flowed/driped out of the other hose. I really don’t know what it should be. Starting constantly with brake cleaner is not a solution. I hope You can help me! Greet Luke
