Well, the distributor could be worn, but if it ran before & after you set the timing, it doesn't occur to me that timing and/or a worn distributor was the problem. We need to first speak the same language. When you say it did not crank, that tells me that the engine did not turn over, i.e., you press the starter button and nothing happens. The starter does not crank the engine. But, I believe what you are telling me is that it did not start. It turned over (cranked) but would not start. So, my first question: is that correct? So, if we assume the engine was indeed turning over, my guess is you 'fixed' some, but not all of the problem w/ the tune up kit. But, and this is what makes it difficult to pin point the precise reason for it needing some choke to run, you have replaced so many parts you may have created a new problem while fixing another. That being the case, here is what I would do: 1. Pull the distributor & re-check the point gap at .015 on all 4 lobes. Slightly stretch the pig tail on the bottom of the coil. 2. Check that each plug wire is firmly in the cap. 3. Pull a plug. What does it look like? Light brown? Black & sooty? All 4 should be light brown. Re-check the gap (.025) 4. Check that each plug boot is firmly on each plug. Are the plug wires ok? Not frayed or cracked? Are you sure they are copper cored? If not, replace them. 5. Remove the wires from the ignition switch & clean the contacts. do the same w/ the wire going to the top of the coil. Do all of this & re-post if it does not work. And, your problem could be a vacuum leak, trash in the carb or a restricted fuel flow, or an incorrectly adjusted carb, but my personal experience is needing choke to run is an ignition system problem.
