71 New Yorker

Hi folks I just wanted some thoughts. My 71 Ny was working good than one evening it just wouldn't start and it's been that way for a few days now. Turns over well but just want catch. I checked the fire with a spare plug and it was firing fine not sure how bright the spark is supposed to be but there was lots of spark. Fuel going to the carb also. Question will the plug still fire if the points are done. The previous owner gave me all his spare parts he accumalated over the years not sure...
