Engine runs rough choppy

[chevyman1964]

I have a 64 nova with a rebuilt 350. It has a mild comp cam and a quadrajet carb. I set the total timing at 34. The engine takes about 6 tries to start the car. Once it gets warmed up to temperature and I go to drive it if I step on the gas from a stop the engine runs choppy. It doesn't feel like it is running with as much power as it should.. Any idea on what to check or adjust?

sounds like your timing is off.
