HELP HELP HELP ! LEAKING CARB 2BBL 318 72 DART need help with this

If the carb is flooding the needle and seat may have trash in it, the floats may also have taken on fuel or they are just out of adjustment. It's not abnormal to have some leakage at the throttle linkage bores especially on a 30+ year old carb. Get a kit, rebuild it and check the floats to see if they have gas in them, they should be brass on that carb. Don't forget to change the oil and filter as the crankcase may have a good amount of gasoline in it and gas doesn't lubricate very well at all.
