I have a vacuum gauge in my truck. Its calibration goes completely wonky - over time the needle creeps up to the point where, with the engine off, I'm showing 10" of vacuum. Obviously that's wrong and I fixed it once, but it did it again and now I don't care. It's most useful at showing me small changes from moment to moment, so the actual values aren't what matters to me, just the direction the needle is moving.

I learned how the pedal felt when the resistance increased just a teeny bit from the second carburetor barrel opening, and that makes a BIG difference on the vacuum gauge. Keeping it out of the second barrel seems to be the sweet spot for modest acceleration without slurping the fuel too fast. I have 3.73 gears in the rear end so it doesn't take a lot of push to get speed changes, even going uphill - kind of the opposite situation from Br'er Fumes. I just have to live with the rapidly churning engine even in top gear.
