How did it run before you worked on it. Does it try to fire at all now? Have you changed, modified, or disconnected anything else since it last ran? When you changed the plugs did you get all the wires back on correctly? Have you checked the point gap? All you need is air, compression, fuel and spark at the correct time for it to run. I am assuming that the compression is OK since it ran before. Try the following:
Pull the coil wire at the distributor cap and hold it about 1/4-1/2 in. away from the cap where you disconnected it (center connector). Have someone turn the engine over. Do you get spark? If not, check all coil connections. If so, now do the same at one (or better yet all) of the spark plugs, disconnecting them and checking them at the plug, one at a time. Do you have spark there? If not, remove the distributor cap and check the points for pitting and check/set the gap to about .016 in. for starters. Also check the rotor for corrosion and worn/missing springloaded carbon contact in the top of the cap. If you do have spark, check to see if you have fuel getting into the engine. Remove the air cleaner, and one at a time open the chokes manually, look down each carburator's throat and manually move the throttle from idle to approximately 1/2-3/4 open. Caution: make sure the ignition is off and do not try to start the engine at this time. Make sure there is no source of ignition around. Do you see fuel squirting into the carb. throats? If you don't, there is a fuel feed or carburator problem. If so, there may be a timing problem. Let us know what you find up to this point.
