Have a 2002 FLHR with S&S Super B Carb. Was running fine until gas line broke in half between output of petcock valve and into carb. Replaced fuel line. Will not start. Tries. On occasion it starts but doesnt stay running for more than a few seconds. Opened carb cover...can definately see gas squirt into carb Checked/Cleaned Spark Plugs New Battery with Tender on it. Any thoughts greatly appreciated.
