Hard to beat Davida Vacuum Gauges, but expensive. Without doubt the best gauges out there.Not a great fan of the Morgan Carbtune, they have to be held exactly straight upright to read correctly, not always easy to do. They can get a bit sticky over time.
Christ. are they worth that? ive got two multis with carbs so I do wanna decent set xjrs apparently need doing quite often too
there was a set of davidas, old but apparently sound, on the bay for sixty sovs. they turn up tomorrow...hopefully they will be ok. also tret meself to one of those hang up fuel supply bottles with a petrol tap.
