I've been searching the web and can't find jack outside of "remove the adjustment ports until fuel starts dribbling out." That's all well and good if the carb has some. Here's whats been happening: Great acceleration, up to 50mph, a minute or three above that and it started "bucking", nose down, (me toward the steering wheel). Also, it would die if I didn't put it in neutral and coast for a bit. A older fella at Car-quest said the float was too low and that I needed to bend the tab so it's parallel with the bottom of the top plate. So I do this, not finding any info anywhere else. It doesn't buck anymore, it surges and seems to want to die. Did I bent it too far? Am I totally off the mark as to whats causing this? Is there an actual float level that somebody knows of? The carb is on a 1977 Dodge B300 camping van with a 400ci. I really gotta get this done as it'll be hauling me, GF, minion and all the gear and stock and my trailered 66 Lark to the NYRF in a couple of very short weeks. Please help. I really don't know a lot about carbs beyond the basics.
