I have a hand held vacuum gauge that has to be 30+ years old that I use for setting my idle mixture screws. The gauge needle holds nice and steady (minimal jumping around) when hooked to a vacuum port, but reads 2hg off, but that's ok as I take that into consideration when reading it but at least you can see the needle vibrating around 11hg.
I bought a new one from a reputable online Mopar speed place but when it's hooked up the needle jumps/vibrates all over the place and is pretty worthless when trying to read it.
Anybody on here have a suggestion for a good vacuum gauge that holds steady when hooked up? A work colleague recently bought a '72 Cutlass and I'm telling him some necessary tools to get and a vacuum gauge is one; but I want to recommend a good gauge with a needle that holds steady (and I might also buy it too).
TIA!
