Engine no power

First a list of what I changed, the engine completely stopped, so no electric, changed coil, new distributor with rotor, cap, condenser, new plugs. I also changed electric fuel pump. It was also not working. Finally got the engine to run well, but it has no power, have been able to drive on flat ground, but slightest grade will not pull. I
found compression with spark plug number one, marked the cap for number one plug and then put spark plug wires in place. Damper pulley was also set to zero.
