Post Quadrajet tuning Problem?????

I recently scrapped a holley double guzzler on a 350 and replaced it with a Q jet that I rebuilt myself. I am having trouble going to WOT from idle. It just wants to bog out, backfire, kick, cus, and the like. I can only open to about 3/4 throttle until I hit about 28-2900 rpm. After that, my secondaries open up nicely and she screams. I am just learning about carburetors for the first time, and am very interested in any input from anyone who knows more than I do.

Sounds like a lean condition, you may need richer secondary metering rods or, you could adjust the secondary`s, to do so, you`ll need a small allen wrench, and and small flat tip screw driver, on the secondary side of the carb on the passengers side, they`ll be a small flat head screw, under it will be a allen head bolt, this adjusts the tension on the secondary butterflies, if they open too soon it will cause a bog, if to tight it will cause a lag in power and flooding, go to this page to lean about Q-jets,http://www.geocities.com/gtopercy/Pictures/quadrajetTech.html this will tell you more than I can give in detail, I respect you for dumping the holley and going with a Q-jet, All I run is a Q-jet, and once you learn them, you`ll see how simple they are, good luck.

Thanks, I went there, and learned quite a few things about the Q jet and will try tinkering more with them tomorrow.
I am glad I found this Bulletin board, because here in Pueblo, everyone I talk to laughs at me for not using a holley or an edelbrock, and I plan on showing them why I am not.
