Edelbrock Carb problem?

I've got a 1406 Edelbrock carb on my 402 BBC. Yesterday, driving home, the engine started to stumble a little and then started slowing down. dropped from 50 to a max of 30 MPH. When I got to the driveway, it died. I got it to restart and limped it into the yard, but it was really down in power. It sat for a couple of hours and I restarted it and it ran fine for about 50 feet, then was really stumbling and I got it over by the shop before it shut itself down. I put a new fuel filter on it and the one on there, although not very old, was full of crap. It wouldn't restart yesterday, but would turn over freely.
This morning, I tried it and it fired right up. It ran about 15 seconds and started to run rough again. the little bowls (if that's the term) right next to the metering rods filled with fuel and over flowed. I took out both metering rods, neither was stuck, cleaned them with carb cleaner and replaced them. I got it to restart and when it did finally start, it ran like it was loaded up. It thenm did the same thing, filled the bowls and overflowed and died. Anybody out there know what I need to do next?
Thanks in advance.

OK, I took it off, opened it up, and it was full of crud too. I cleaned out everything with carb cleaner, put it all back together and fired it up. It ran fine for a few seconds and then did the same thing again. filled up the bowls and died. What else could it be?

Boy, I hope nobody put something in my tank........I'm out in the desert on 5 acre lots.........I pulled it down again.........took it all apart......blew out everything I could with air and put it back on...........success!!!!!!!!!! it's now running fine, idled it for about 5 minutes, drove it about 4 miles...seems to be ok. I'll keep my eye on the fuel filter pretty regularly for a while, just to be sure. Tomorrow, I'll change the plugs, cuz I'm sure they are fouled, and I'm gonna pick up some more fuel filters...........at least I didn't have to use my AAA membership again! Thanks everyone!

not a problem.....junk is a carbs worst nightmare. If you keep gettin stuff in the filter, try duel filters one before the pump and one after. also try to get some good clear filters they can be helpful in keeping track of whats bein pumped thru it.

Happy rodding and good luck!!

Good advise....I've got two filters on my 66 Chevelle, don't know why I didn't do that to the truck, just lazy I guess. I use the clear plastic filters (Fram G12) on all my stuff.
