I think I might have a vacum leak. What are the most common spots and even the least common spots for me to check. Its a Carbed 82 305. Thanks in Advance.

 

well i've found the best way to check for a vaccuum leak is to take a can of carb cleaner and start spraying around the carb and any other place around the manifold area. if the engine picks up and runs faster/louder/higher rpm, then u have narrowed your leak and know that u have a leak. i've personally dealt with leaks around the carb gasket on the 68 torino gt 390 2 bbl. the local autoparts store gave us the wrong gasket and didnt seal up to the manifold correctly
