Hopefully get some help here. This forum doesn't seem so busy. I have an 86 nissan 720, Z24 engine. California model. I've gone through it to make sure I don't have vacuum leak, have rebuilt the carburetor too. The issue is I have to feather the gas off idle or it wants to die, like hitting a flat spot/going lean.
Float level is correct
Accelerator pump squirt not the greatest, but it's there
No vac leaks
Choke works properly
Idle cut solenoid works properly
Any ideas? I know even a rich condition can cause this as can a lean issue, so maybe lower float level a little more?
