Hi all, new to the board. Seeking help on issues with my 440. Has Holley 4160 just rebuilt, on a new Edelbrock 2191 intake. New plugs, wires, distributor. Fires up as soon as I turn the key, runs/idles perfect but as soon as press the brake pedal and start to move, starts idling rough, blows black smoke out of the exhaust pipe, have to work the gas pedal to try to keep it running but it dies. Have to hold the gas pedal to the floor to get it to start again, but very rough running. Plugs are wet and black. Any ideas what I’m dealing with???? Completed brake booster and check valve tests, both seem fine.
Thank you for any input.
Bill
