There are three basic things needed to run: Fuel, Spark, and Compression. 95 ain't that bad and will run a lot less than that. So, let's concentrate on the first two things; basic problem solving methods apply. Verify fuel first, it's easy to see if carb is getting fuel. With engine COLD, not a problem since you can't get it running now anyway. Loosen the fuel line at the carb brass elbow inlet and point down into a container like a coffee can. Open fuel valve two full turns at the sediment bowl assembly. Observe fuel flow as a steady, pencil thick stream uninterrupted. Hesitation, starts and stops, or slow drips indicate problem is in fuel tank and sediment bowl, not carb. If fuel flow looks good, move on to spark, if not good, time to clean the two screens in the sediment bowl assembly. You'll need to drain the gas tank before pulling sediment bowl assembly to get to the internal screen soldered on the top of sed bowl line in. Careful cleaning and blowing off. I've had some screens blow right of the assembly. Large half-dollar size brass fine mesh screen lies horizontal on top of assembly can be removed, cleaned and blown off with compressed air. Once fuel issue is eliminated, we can concentrate on spark. I'd go back to distributor and go over everything once again and at least check timing. Sometimes that copper strip gets twisted or mangled and will be the culprit. A simple continuity tester will suffice to check for shorts while unit is on the kitchen table or workbench. My money is on the distributor but eliminate the fuel issue first.
