So gauges #1 and #3 gave the same readings, but #2 was 0.75 down and #4 was +1 up.
As long as I remember to add or subtract as required, I can get an accurate result.
A mercury gauge is around £100 or there are digital ones for £400+ !
Try as BBrown has suggested, it my well work. Or as you've said, but they need to constantly read the same once they do, then plus/subtraction method should work.
Gauges are expensive, mine which are 30 odd yrs old are proper workshop models, cost me over £250 back then. I've had many a bike in where an owner or a stealer has balanced carbs/throttle bodies only to find they're a good way out. They other issue is owners over adjusting, i.e doing them with poor gauges when they don't need doing, but their gauges say they do, or they do them wrong.
