bad city milage 2bbl

ok sorry for not replien for a while chem got me like what life? i cleaned all the connections on the plug wires and it seemed to like that. and i do think i have a vacuume leak that i tested with propane enrichment and its either the carb gasket or the vaccume pull off. now i got a problem of my gas dissapering from the fuel filter but my oil doesnt seem thin or smell like gas so i gotta track that down though when im working on it in the engine bay i can smell a hint of gas.
