Gas Leaking from Intake Manifold

I have a Briggs and Stratton 15.5 HP engine on my tractor. It has developed a gas leak, which appears to be coming from the connection between the intake manifold and the carburetor. Does this connection just need a new gasket or is there a more serious problem with the carburetor? Could the wrong fuel filter allow to much gas into the carburetor? I just replaced it with a generic B&S part from Home Depot.

Sounds like the needle is not seating in the seat in the carburetor. You need to remove the float bowl and inspect the inside of the carb. Might need to be removed and cleaned/reconditioned.

Also check the oil level to verify it's not over full & smelling like fuel.... If so, change it before you run the machine, as gas in the oil thins it out & causes a lot of damage.. Roger
