[84cutlass454]

i got a 750 cfm carb and when i brake torque the car is like breaks up or like hesitates at about 3400 rpms then i punch it to about 5000 rpms it just fine the smoke starts to roll i dont know what the problem and when i go to adjust the needle and seat with a vacuam guage it dont change and i can close them all the way and it still runs and i cant put my hand over the carb anf it dies so i know it dont have a vacuam leak

need to clean that carb out lol
with the car running take out each mixture screw and shoot some through there if that dont work need to pull carb pull both screws and use air pressure to blow out each idle cicuit after that it wouldnt a bad idea to run a can of seafoam through the fuel sytem

Scrap that eddy carb and throw a holley 4779 dp on her, your problems will go away...... I had a eddy 750 on my ride and all it did was bog down off the line then after a sec or so it would run like a raped date............scrapped the eddy, put on a holley and now the bog issue is gone.....
