Congrats, way to dig in and give it a try. Those old single carbs are pretty simple. As long as you did a good job cleaning out the fuel feed, needle passage, air/fuel mix passage, and main jet passage it should be good. Did you adjust the float level as specified? That is crucial on these. I noticed in the pictures a couple of main bowl screws aren't tight or seated, probably took pics before finishing. The only thing I suggest is check and change any rubber lines that are old they will deteriorate and fill your carb with nasty rubber crap again. I figure on most things if they are already not working what am I going to do if I mess up, not make it work? Rip and tear my man and remember 8N's aren't made for wheelies
If you believe in the 150 pellets in the 10 inch circle, I guarantee you will miss more turkeys!!
