Because they were selling cars to people like you who don't know how to tune them?
Sorry, couldn't resist the bait. I'm a sucker for a spinner bait being trolled at just the right speed.
It takes some time to get a carb set up right. Unfortunately you are going to need to spend some reading carb set up guides. Also consider seriously investing in a good wideband O2 meter. Bigger accel pump shot might get the car to the point where you can really start tuning it. But everything starts with getting the main jets right at WOT. The best way to do that is with an O2 gauge.
