Re: Cannt start 360v/8 dodge cw two barrel Holley floods...
Chill out ! that vintage Mopar is a thing of beauty. Are you sure it's flooding out? If so, it could be a stuck float valve in the carb. If it's stuck open, raw fuel floods in and stalls out the engine. if Icn recall correctly. a few phillips screws can a cess the top of the carb. with the top off, crank the engine a couply of times. That should dislodge any dirt from the fuel system which could cause the float to stick and flood the engine. Put it back together and hope it works. Love old Mopars, John

the float needle and seat is the first obvious fault
next if a holley, is the power valve has a hole in the diaphragm
next is wrong pressure from the pump ( add a fuel pressure regulator)
best have the caby overhauled by an accredited carby specialist shop because it is very easy to miss the exact reason for the flooding and be back in the situation where you are now
if the carburetor keeps flooding out, the float could be stuck in the up position. tap lightly on & around fuel reservoir to free. depending on age of carburetor, you might need to put in a carburetor kit.
carb is sitting to close to hot intake manifold, need phenolic or some type of spacer ,, fuel starts perculating when vehicle shut off perc.s out of vent tube causes it to flood ,then when you do get it started its rich so you stomp on the gas and blow your power valve out try letting it clear out a bit before accelerating , if it backfires replace power valve
Depending upon which bowl design you have on yours, you need to check the float level. There should be a brass sight plug on the right side of each bowl. To adjust, remove one plug, loosen the screw on the top of the bowl and turn the 5/8" nut that surrounds the screw. BE AWARE...when you make this adjustment, fuel will squirt from the screw you loosened, so you need to have a rag nearby to keep everything dry. Fuel will also spill from the sight plug hole 'till it's properly adjusted. Turning the nut clockwise lowers the level, ccw raises it. If you cannot stop the flooding, you will need to remove the bowl and clean it out. You can get a complete rebuild kit from Holley (you'll need the number stamped on the front of the air horn). The kit includes new needle and seat valves, power valves and all necessary gaskets. Always use a new filter to prevent new crud from ruining your work. If you have bad or questionable ignition wires, replace them before attempting adjustment. Float adjustment is done on a level surface with the engine running.
trouble as that engine light has to be on did you connect it proper first plug in obd 2 scan tool turn sign on do not crank eng! press the scan button it should have something for you these are sensitive and come on quite easy!
