Looking at buying a set of vacuum gauges, not sure to buy dial gauge type or stick gauge. Anyone got any preferences or recommendations?

I used to use the buodon tube gauges, however after purchasing a set of "CarbTune" from England, I find them streets ahead. They are designed to look like mercury columns, but are really slugs of alloy, hence, they are compact and accurate.

Those ebay ones are cheap and nasty.
If you go for gauges then buy DAVIDA.
They are the best.

I've had a set of morgan carbtune gauges for years - still work fine and very easy to use.

A bit more research has turned up plenty of good feedback on the Morgan ones,
people say the cheaper dial type fluctuate, can anyone confirm this?
I am thinking for the amount of times I am going to need it the Morgan one is the most suitable, tho a mate will go halfs so I can get Davida 4 cyl for £55.
Thanks for the input lads.

I have had the Morgan one's for years and would recommend them to anyone. Easy to use and compact for storage into most tool chest trays.

I've also got Morgan carbtune gauges which I've had for years, nothing to go wrong with them and no fluttering.

I have morgan gauges, which i purchased in the mid nineties and have used hundreds of times on many many bikes, i recommend them, not expensive either.

Well that's it then, based on all the positives on the Morgans I will get that type, thanks again for the info. I used the colourtune before, the carbs were all fairly close maybe a half turn out on the middle two.
Did what the booklet said and went halfway between where flame was yellow and where engine started to falter. Which was 2 and 1/2 turns between the two, so 1 and 1/4 back. Maybe slightly crisper off idle.

I've had the first ones and while they do the job (just) I found it rather annoying having to calibrate the damper valves first (little white taps) before you could actually check the carbs, even though you had all four set the same the dials still kept jumping 2-4 units so not easy to read.
Also tried Twinmax, brilliant tool, very precise, perfect for 2 cylinder machines, bit more involvng with 4 cylinders:

My last buy (8 years ago) was DAVIDA balancer, they have internal auto dampers so no fiddling reqired just plug and play, best 4 carb set I've seen and am still using :

I have had my Davida's for 30 odd years and they still work perfect.
Mate of mine bought some of those 'no name' gauges same as on ebay and although looking good value they weren't accurately calibrated to each other, so if after balancing we switched the tubes around and they all read differently ,So a pointless excercise unless he wants to unbalance his carbs.
Each bank of Davida gauges is individually set up so they all read the same at the same vac.
Switch tubes on those and all the readings will still be the same.
You get what you pay for.

If you like to buy something German, you can also get a set of Boehm clocks. I have a set for at least 7 or 8 years and they are the dogs. You can set up each clock's damping individually and they haven't disappointed me ever.
Just my 2 cents worth
