Hi everyone, I have been working on a 79 Garelli Gransport the past few days and have hit a wall. I bought a new spark plug for it and had it running yesterday but today it wont start. The engine will rev when the clutch is pulled and given some gas but the engine just wont catch anymore. The carb was leaking a bit so I took it apart and it looks fine. It's a great bike and really fun to ride so I'd love to get it back to a consistently good condition. Any ideas on where to start with this thing? Thanks!
