Trude no spark

Hi Mens, I have the following problem. My Trude (US model, Bj 96) no longer has a spark of ignition. I was still at work in May, after that she stood for 5 months and now nothing works. Even with starter help (though my battery is scrap) nothing works. The starter spins and after a few seconds orgling it smells like fuel and the candles are wet. I don’t know any more advice. Before commissioning in May I had to weld the tank fixture. Battery and control unit were off You know what? Would you be very grateful for your swarm knowledge ??
