I had to let my scooter sit for a few weeks last winter. When coming back, I knew he will be a pain to start. So I recharged the battery fully. However, little did I know that he will be such a stubborn piece of sh... After a few unsuccessful attempts, I start shaking him. He sometimes liked this in the past and turned on. This time, however, it takes ages until he catches. After one attempt shaking him wildly, he starts on me. But guess what? Despite all my good-meaning gas pumps, he just stalls on me again. This happens several times, until I am completely fed up and start kicking against the little engine during my starting attempts. This, in turn, seems to make him fed up with me again. He stays stubborn and stalling until I had to give up in the end.
