backfire... KA-POW!!!

what causes backfire on a carburated motor. the choke is unhooked and when the motor warms up it will backfire and lack just about all its power going down the road. mixture too lean? too rich? i cant even pull the truck out of the driveway. maybe the plugs arent fireing? double checked all the wires and they are all going to the correct cylinders.wires and plugs are all new. so is the cap and rotor. yea i think im lost
