Sometimes when i hit it off a light it will about stall. I dont want to say bog down probably something more like a miss i think. Sometimes ill just be driving and it will do the same thing and i always left off the gas as soon as i notice this happens. Is it the points?

Does the stutter occur only while accelerating or will it occur with steady throttle as well?
Lift the distributor cap and inspect for a chaffed primary wire rubbing against the breaker plate or housing. Also, give the primary lead a gentle tug to see if it stretches or separates.

What brand carb do you have on it ?

it will happen at a steady throttle too. Happens mostly when its colder outside even after warming up sometimes

(http://uploads.tapatalk-cdn.com/20160426/80a6e4e0f7de3394ff07a33ddc507600.jpg) heres a pic. That lower wire is wrinkled a bit. Ive never taken the time to look into how a distributor works and know very little about it so i dont know which one is the primary wire

The primary wire connects the points to the ignition coil. It's the 'wrinkled wire' in the image. In itself, the wrinkling is not significant. Look inside the distributor cap for any evidence of condensation, cracks or carbon tracking. Carbon tracks are black soot residue left by high voltage repeatedly arcing across a surface. Typically carbon tracks are irregular in shape with a pattern reminiscent of lightning. When did the engine last have a complete tune-up?
