OK
For starters then I would say you have too much carb for your stock 318 setup.
Get ahold of an Edelbrock 1406, they are proven to run well on the stock 318s with their stock camshafts.
Beg, borrow, or steal a good known working 1406 carb and get it on there.
I see you are 19 years old.
What year is your 318 engine?
What year and model is your car?
