ok i know it's the carb cause i've been tuning it and it's been getiing better but right now when i'm at about 2/3 throtel it starts to sputter and sloly exaleract then i'll go full it down shifts like i shold then gets high revs and goes then yeah i dunno what that could be

 

Please describe the problem in much more detail, and in more than one sentence. We cannot begin to diagnose a potential problem without more details. What kinda carb/engine? When doe sit happen? Is it cold/warm/all the time? Details help.

 

i have a 84 z28 camaro with a 350 4bbl. recently it has been sputtering at like
2/3 throtel and then it will slowly acelerate. then when i kick it down she down shifts then keeps going but the sputter is gone and it shifts really low out of 2nd gear. i know its the carb i've been tunning the secndary choke screw (don't know the name) but it has been getting better but i can't seem tog et it to work after playing with it for like 4 days thank you hope it's more to help you

 

I don't know if it will help but it might. try putting some carb cleaner in there and see what happens. Sounds to me like your carb is starting to gum up and will need a rebuild. I had a q jet that did something similer but mine was boggy off of the go and would get better as I accelerated.
