IF it's what I think it is then it should work fine - if you can get access to the carbs easy enough. It looks like it just places over the carb mouth and checks the air flow.
I use these to balance my Spitfire. You basically put it on one carb and check the air flow. Then put it on the other to check air flow. Adjust and check until they are in balance.
Once in balance you then adjust for tuning / idle - making sure what you do to one carb you do to the other (so turn by one screw on one carb the other has to be turned the same).
Once finished double check that they are still in balance.
On a twin SU carb Spitf (same engine as a Dolly - but much easier access) it takes about 10 mins from lifting the bonnet to closing it.
