Got a new edelbrock (SPELLING) carb today. They are supposed to be no tuning required. The guy at the counter is one of those "master mechanic that could only pull down a part sales position" kinda guys. He screwed with the two little screws and said that they were now right for my 350. He just screwed them both down all the way and screwed them back out 2 and a half turns. If this doesn't work, then what? Should I go to the manager and say PAY MY MECHANIC TO FIX THIS? I could just turn it in and get another one i'm sure, but then I have to spend more time taking it off and putting another one on. This is pissing me off thinking about it and I haven't even put it on yet (had to go to work) Anyone here know about carbs and if this guy just screwed mine up. Will I need to get it tuned now or get another one?
