Hi all, I’m new to vespas but not new to motorcycles. My newly acquired 50 special ran ok for the last 2 months. It felt like it was never hitting the power band though. Recently it would starve out and die at high rpms unless I pulled the choke. Once the choke was pulled it ran better than before and would hit the power band. However, it would die at idle unless I kept on the throttle. It will idle normally with the choke off. Any ideas??
