dont get frustrated cause this will help you learn it inside and out. i know i have an edelbrock carb and had some trouble getting it to be set right. before even thinking about it check for exhaust leak like vac72 said. that way you know if it is valves or exhaust. i know if your timing is of you could have valve ping. check out these two links and it should be a good start/help to get you in the right direction i know it helped me out, also something to think of checking for any vacuum leaks. but i would do the exhaust leak check, timing then carb/vacuum if you dont resolve with the first 2. if you change anything in you carb make sure to right it down any adjustments, amount of turns and any jet, spring changes. ask me how i know it is easier in the long run.
