SEEMS TO BE AN ONGOING PROBLEM FOR A LOT OF US.[/align]

 

Before looking for possible electrical problems, make sure the easy ones have been ruled out.
It's very common when carbs are rebuilt, for the float levels to be upset. The little plastic arms of the float valves are very easily thrown off. I would take the bike to a different mechanic and ask that the float levels be checked.
OR, if you have the service manual and a clear tube, you can do it yourself.
Good luck and let us know how it goes.
Peace!
