73 charger spitting through carb and backfire through exhaust

[texas charger 73]

I have a 73 charger with a 318. It keeps spitting through carburetor and backfiring through the exhaust. I pulled plugs. They are black. I can't check timing till I can get it started.  I put number 1 on TDC but one time I get number one on driver side of cap and second time I'll get it on the passenger side. Any tips please. This car ran beautifully when I sold it 13 years ago. Motor was freshly rebuilt. Car had 75000 original miles. Guy I sold it to pieces it out so I'm slowly trying to find parts to out it back together.

Welcome to the board.

The #1 piston comes to TDC twice on each firing cycle, one time it's TDC on the compression cycle and next it's TDC on the exhaust cycle...when #1 is TDC on the compression stroke #6 is TDC on the exhaust stroke, that's why the rotor is opposite.

Easiest way to determine which one it is is to remove the #1 spark plug, place your thumb over the empty hole and slowly turn the crank until you feel air escaping...then watch the timing mark until it lines up at zero. This is TDC #1 on the compression stroke. All ignition timing is from TDC compression stroke.

Then make sure the distributor rotor is pointing to the #1 spark plug wire in the cap, then check the firing order starting at #1 and going CLOCKWISE 1-8-4-3-6-5-7-2.

A couple of reversed wires will do that. Make sure they are correct as posted.

Thank you guys for the warm welcome. I got it running. He had it 180 degrees out. Now it runs like a beauty.
