Carburator Adjustment Help

[dave3156]

About two weeks ago I bought a new Edelbrock #1406 carb. with automatic choke. I put it on and installed a new fuel line and new inline fuel filter. The carb that it replaced was also a #1406. It ran fine with the old carb, but could not get past Federal exhaust emissions testing. With the new carb it easily passed the test. I am disappointed with how the engine (350, mild cam, headers, performer RPM intake) runs with the new carb. I have read on other posts that it probably needs adjusted. The idle is too high and at speeds over 80 mph the engine bogs down and will not accelerate, in fact when you hit the gas pedal nothing happens over 80 mph, it continues to go at the same speed. It acts like it is fuel starved. Also low speed WOT performance is about the same as with the old carburator. I had hoped it would be better or I would at least notice a difference. I can hear more sound when the secondaries open but performance does not seem much better. I'm guessing it needs adjusted. I went to the Edelbrock website and alot of ajustment kits and parts are available? How do I know which kit I need? I am going to have a mechanic adjust the carburator, but want to get some opinions about what I need so I can have the parts he might need when I take it in. Can anybody help?
