I Have a 1965 Ford F100, The body is in good condition, I know enough about restorations to handle this but i finally came across an issue i dont quite understand. The motor turns over easily. but it will not start. I have replaced the fuel pump, ignition coil, Plugs and wires, distributor, and routed new fuel lines. I am getting spark. I also cleaned the carb top to bottom. i was wondering if there might be something im over looking. Any help would be appreciated.

By the way the motor is 3.9l 240 straight six.
