Another edelbrock carb question!

Because of the shape of the weight (and the placement of the mass as a result) the door is harder to start openiong than to continue opening once it's started. The weight basically looks like a "J" with the top of the J being a pointed, a narrow area, and the curve being the thickest part. If you remove from the tip of the "J" it will open earlier and a slightly faster opening rate. If you remove from the curve it will open at a faster opening rate but not necessarilly any earlier. I did it on my plow truck and a couple cars that I ran AFBs on and it was enough that I believed I could feel it. But that's using the butt dyno so who really knows. I'm sure it did something - I removed weight... but I can't say it was a night-and-day difference or anything because we're talking small amounts. Like 1/8" off the very center of the curve, or some off the "tip".
