I have a 78 z28. It has a couple of things that I’m hoping could be fixed by doing one thing.

I haven’t messed around with carburetors much, but when I stomp on the gas when I’m already rolling it will choke out and /or stutter. Or if I’m at a stop and press it pretty good but not a stomp it will die and takes a while again for it to start.

I was thinking that it could be one of two things. Either it needs a good carburetor clean and adjusting or the points, rotors, spark plug and wires need to be replaced and check timing. Anything helps. Thanks

 

Does it hit on all 8 cylinders the rest of the time?
Could be a number of things,check fuel filters and choke function first.
Maybe wire the choke open for a run and see if that makes a difference,if the choke is closing when it shouldn't it was cause that type of problem and it's common with OEM Quadrajets if that's what you have.

 

It runs really good when I’m just cruising slow so I imagine it’s hiring all. I’ll check the choke.

 

Sure sound like a choke sticking shut,probably needs a new pull off.
