Just wanted to say thanks again! Rob was kind enough to help me work on my 1978 CB550 this morning. We took the carbs off and gave them a good cleaning and Rob set the points. The bike is running a lot better and throttle response has improved, but it still has an idle issue that needs to be tracked down and my headlight stopped working so I'll need to go through and clean the connections. Overall, I'm very happy with the CB550!
