Ford R8 Riding Mower Won't Start After Replacing the Fuel Line

Well if the mower worked prior to replacing the gas line I suspect something wrong with the gas line. Could it be plugged, or have a kink in the line?
I would first see if gas is getting to the cylinder or in to the carb.
I think the gas is fed to the carb by gravity so there may be a air block in the line.
Iwould disconnect the gas line at the carb and see if gas is coming out the end of the line.
