Got it crankin but back fires through the carb, timing help

[Boise69]

Someone once sent me the firing order diagram on the 350 and the distributor cap order for the plugs,

when i replaced my HEI with a new HEI i just replaced the cap assembly not the the entire distributor. i moved nothing,

do i have to re-set the timing or did i screw up the wire order on the new cap, its possible because some of the tape fell off and i guessed on where the wire went

but now i'm getting a strong crank from the new mini starter but getting spurting out the carb.
