# 1 cylinder has no spark

OK i have a 75 nova with a 350 motor. im having trouble trying to set the timing, when i hook my timing light to #1 cylinder nothing happens, i just recently replaced all spark plug wires and plugs. now if i stick the timing light to any of the other spark plug wires the light works, i was having the same problem with the old wires i have tried making sure the distributor was in the right spot, top dead center on compression stroke with the rotor pointing to the #1 cylinder. the distributer is a brand new excel hei i can start the motor but it runs pretty ruff and puts out a Lil white smoke. if you try to romp on it smoke will come out of the carb and it will hick up. any suggestions would be great.

Is the #1 plug wire seated properly in the cap? If so, I'd check resistance in that plug wire, new or not. Pull the wire and short it near the block, look for spark (putting a paper clip inside the connector helps). Check the wire end connectors as well, sometimes they're bad, you can buy them by the bag at the parts store.
