burfordc

My front pipe is cool after running for a few seconds and the back one is really hot. It is running like crap and only if I keep the choke half open. The spark plug is firing up front. Here are my questions: Do I have one or two carbs? It looks like 2. I only see one fuel line off of the spit-cock to the carb in the back, does that feed them both? Is there a fuel filter for each carb (If I have 2)? Any ideas on what might be wrong? Thank your for any help out there.
