    How did you clean the carbs? did you take them compltely apart and soak them in carb cleaner and replace all of the o-rings? It sounds to me like the pilot circuit is completly clogged up so it can't pull fuel into the cylinders.

      It sounds like your not having problems with your floats or needle valves anymore. It sounds like your not drawing any fuel out of the bowls. I agree with dgeorge. Sounds like your carbs pilots are clogged.

          Did you happen to run a thin wire through all the jets and holes? The main jets will pop out and have more tiny holes on them that you have to clean. I was told that its better to be thourough or else you will end up taking the carbs off and working with them more then once. Did you happen to replace the o-rings while you were in there?

            Nicholas, Yes you should take them completely apart and soak them in carb cleaner. What has probably happened is that letting them sit over the winter clogged up the pilot circuit. When gas sits for more then a few weeks it starts to turn to varnish and can clog small passages very easily. I would also contact Robert Barr and get the o-rings for your carbs ( I think you have the CV carbs) and replace them. The carb clean up article on here is excellent and provides great pictures of the process. If you follow the procedures discribed I am sure that it will solve most of your problems with the carbs.
