Tuned up last year (original 402). New plugs, wires, had Holley Carb adjusted by an expert who races with Holley carbs. Left for a cruise-in today. Car idled at 700 RPM as it always has. Nice lope etc...from cam etc.. Got home later from cruise-in and car would struggle to sit in my driveway and stay at 400 RPM. It would shut off/stall too. Wondering why all of a sudden?? Any ideas as to where to start looking?? Figured I may change the fuel filter and run some type of carb cleaner through the tank first. Anything else?? Thanks in advance. :)

You start by openin the hood and removing the air cleaner.Maybe crud got in the needle and seat and fuel is spilling out the boosters.Did you open the hood yet?
