Ummmm, the guy screwed up the rebuild? Something not connected properly? Got a manual?I have a 1994 Virago 750.I bought this bike from a guy that had not ridden it in a couple of years. I had the carbs rebuilt and put them back on a couple of days ago. Spark plugs are all good. But now the bike has a rough idle. I can rev up the rpms but when it goes back to idle it wants to sputter and then cut off. Any ideas?
