Replaced plugs, wires, cap, rotor, points and condenser. Good spark from coil to block and plenty of fuel. Car cranks but will not fire. I am suspecting a bad distributor? Any other checks I can make? I do know that when the car was running I could advance the distributor by hand and there was no change in idle speed. The distributor has never been out of the car but could it have jumped a tooth or something?
