I have a 2003 carbureted Dyna Wide Glide. I overhauled the carb and it would not start. It take long to figure out that there is no fuel going to the carb. The petcock is on, and there is plenty of fuel in the tank. Isn't this supposed to be a simple gravity feed to the carb? What could possibly be blocking the fuel from feeding the carb? I have had it in a short storage but only about a year. Help please.
