So I've had this Vespa Grande for some time and it's never had this problem before. I loaned it to my roommate for a while since his car broke down. He was riding it one day and it died on him, then he couldn't get it started.
When I tried to start it, the starter clutch wouldn't engage at all. The clutch bell was spinning so it's not in bicycle mode. I took the clutch off to see if maybe it was seized up, but everything seems to be moving just fine and there wasn't any grease in the clutch. I put it back together and I could spin the pedals really fast with no change in resistance.
Any thoughts? I don't have a drill powerful enough to start it, otherwise I'd just use that.
