Mail Jeep needs help - firing order?

[flightmech]

I bought an old mail jeep 1078 and am in the process of rebuilding it for a part time job as a rural carrier. I believe I have a 4 cyl 2.5 litre engine and it was running when I bought it but severe hesitation with accelerator use even when warm. I did not check the firing sequence before replacing the plugs/wires, rotor and distributor cap. The jeep willl not run now with the 1-3-4-2 firing sequence. It will however run if I fire it at 2-4-3-1. Backwards? What gives? Possible distributor 180 out? I don't know what has been done to this engine previously
