Need help asap!!!

I just finished putting on my new carbourator on my 75 gmc, but I now have a HUGE problem!! when I crank the truck over, just before it catches the carb backfires, then stays on fire for a few seconds! We reacted quickly and put the fire out with water.. no one was hurt thankfully, but could it mabey be the vacuum lines? my timing, or fouled plugs?
