74 Duster (318) cranks, but no start. Need help.

If you removed the dist you likely got it wrong. There is NO REASON to screw with "is it" in time or "is it" 180 out. Learn to put the dist in first time every time and then set the timing, and THEN "start it up."

I've posted this hundreds of times

1...Remove no1 plug. "Rig" you starter either jumper the relay with a screwdriver with one hand or get yourself a remote starter button. All parts stores sell them. "Bump" the engine while you have your finger in the no1 hole until you begin to feel compression. You may have to go 'round once to confirm

2..Now watching the timing marks as they are approaching the TDC mark, do NOT set them on TDC, but rather "where you want" initial timing advance

3...Now set the dist in so the rotor points as near to the no1 tower you can get. IF it does not DO NOT worry, use another dist cap tower, or else "screwdriver" the dist gear up and out and move the gear until you can do so.

4...Move the dist CW (retard on a SB) and then slowly bring dist advanced (CCW) until reluctor is aligned with center of pickup coil. Rotor should now be approaching a tower. Put no1 wire in that hole, and run the others around in proper firing order.

If you did this right, if it has spark, and a bit of fuel IT WILL START
