Quote: Are the accelerator pump nozzles changable on 1405 Edelbrock carbs?
yes,so is the step up springs,needles/jets.
most 1405s I have run had the accel pump rod in the middle of the 3 holes.
they are also know to be a little lean depending on what # carb you have. older 750 has a casting flaw from factory and are poop.
1405s 600cfm are pretty good for street duty IMHO.
PM sent to you.
Well my Edelbrock is about 3 years old- I heard of that casting issue but I think mine's new enough where that doesn't apply?
I also got to thinking- since I'm experiencing more of a stuttering than a flat spot I'm beginning to suspect the ignition system- particularly the spark plug wires. It idles just fine but when you rev it up I'm wondering if I have a bad wire that's not allowing one cylinder to fire reliably....
