Hello,
I'm running the stock 4329S on my non-modified 440 Mag. It is very similar to the other AFB's from what I can tell.
I just rebuilt it, used solvent, then carb cleaner. (Floats were not even close)
However I now have two issues:
1. Accelerator Pump-side idle jet does absolutely nothing. I can feel a slight vacuum when I remove it, engine still idles. Turn it all the way in, engine still idles. Air bleed clog, or any other ideas?
2. Slight surging on deceleration. I did find and plugged up some vacuum leaks, and now have a stead 12 inches. I know it's not a lot, but I did not have this issue before rebuilding. Could the misadjusted (too full) floats have hidden this?
Acceleration is great, starting both cold and hot great. Just the idle jet and deceleration/holding speed surge issue. Thanks in advance for any guidance.
