Is the needle adjustable if it comes not on zero?

It's not adjustable as there's no way to remove the casing without damaging the gauge. The only way I know of to sort of "zero" it out is to get a Lightning (the '99-'04 ones, not the new ones that catch on fire on dealership lots) and run 100 shots of NOS on top of that Eaton twin screw SC! That should "zero it out" LOL

This is the right tool for carburator balancing (equalization)?

Will this work on a2012 Chevy Equinox? Just screws into one cylinder at a time?

Its a vacuum pressure gauge. Not a cylinder pressure gauge.
