How many of us are there? Owners of Dodge based RV's?

Today i couldn't start the engine :-( Big frustration. After connecting booster cable the engine started but the idle speed is low and the engine is very difficulty starting (cold and warm).
The carburator is leaking, so i have to change gaskets. Could you tell me the model of my carburetor? Sorry for no better photos, but I had no instruments for dismounting the air filter housing.
