Hi, I just got back from a four week vacation in Europe. Fantastic stuff, although riding a motorcycle there is nearly suicidal with the disregard of other drivers. I digress. My Suzuki VL250 doesn't want to start. It was running without a single qualm the day I left. It's a carby. Have petrol, have battery power so lights and starter work, but otherwise I'm unsure how to diagnose what's wrong. I have a primer position in the petrol cock but I haven't used it, and to be honest, I'm unsure what it does. Any thoughts or suggestions? It's too nice a day in Melbourne to waste away.
