Well when you go through the carburetor it should have a stock calibration in it hopefully. if all that checks out then you should be fine. If the carburetor hasn't been looked at then you don't know. The last guy I heard talk about his Edelbrock said something he heard about taking the front Jets and putting them in the back and putting the back jets in the front or something like that and you just can't trust anything unless you see it yourself. Yes that's a good idea to take the carb apart and make sure everything's where it should be. And absolutely make sure it's squirting out those two front little squirters when you push on the gas. That could be completely it.
