1970 Chevy Monte Carlo Car Jerking

Hey I have a 1970 monte that I purchased about 4 months ago. It has just under 14,000 original miles on the vehicle. It has been driving great up until a month ago. Every now and then when I began driving the car it would bein jerking in a constant rythmic motion, until eventually it cuts off. I then have to keep cranking it back up until I eventually get to my destination. I got a diagnostic and they said that the carb needs repair because it flooding the engine. I had a second opinion and they said that the points are almost burnt out. Side note: as of late it has been taking about 20-30 turns to crank the car up with it staying on. Plz help, What do you guys think?
