Stumble issue

Yep, I cleaned it out. With the car off and manually twisting the throttle it seems to me like it gets a nice shot of fuel and it looks instant. I used a 7/16" drill and just used a 6" rule to measure the drop. I understand that it could be the pump when it bogs off thr line, but what about when Im cruising at very light throttle and I can feel it stumbling? Thanks for your patience and helping me out guys.

Look at your chart and go 1 stage richer (cruise mode) untill the bog goes away. Hopefully you will be able to do this with just a rod change.

You can try a new acc pump.Looked up the part # for you.Then you know the pump is good.

Edel Accelerator Pump Part #1467 $8.50 Summit.

Would still like you to get this carb to exact specs out of the box,and go from there.With the new Acc Pump.

One other note.There are countless times when the carburetor is blamed for a faulty running car. When in fact it can be a number of different things.
Ignition,coil,wires,cap,rotor,timing,vacuum leaks. I will assume all these have been taken out of the equation.
