Any holley pros here? Gotta 670 street avenger carb about a month ago
And I'm ready to throw it in the can 74 primary 80 secondary jets
.031 shooter sputters mid throttle and off idle stumble driving me nuts
Anyone familiar with these carbs

Installed on 91 l98 350 aluminum ported heads 10:1.1 compression roller
Cam headers single plane inatake
 
Carb is not new but rebuilt clean as a whistle...float height is right has an off idle stumble also
Has a stumble/brake up about mid throttle when the secondaries open it clears out
