Gunson Colortune See Through Spark Plug Kit
Gunson Car Balancer.
Internal combustion engines use a mixture of air and petrol to generate their power.
The performance therefore is influenced by the air flowing into it and the petrol that is metered out by the carburettor.
Unless the air flow in Twin or Multiple carburettors is correctly set, the correct mixture adjustment is unlikely to be achieved and this is the simplest tool to achieve that.
Suitable for use on SU, Solex, Auto-Lite (Fomoco), Stromberg, Weber and Zenith and can be adjusted to fit most carburettors including sidedraft, downdraft with air intakes (Venturi) from 25 mm to 67 mm (1”-2”) diameter

Available from our stock, ready to be shipped.

Gunson Carbalancer Carburetor Synchronizing Tool - G4053
Anybody who regularly works on the DHLA and DRLA knows the problem of seized mixture screws.
Especially the later versions with the screws in "towers" are prone to seizing as the towers trap moisture and the bronze screws slowly seize in the Zamac carburetor body.
If you manage to remove the screws, this tap will help you to clean the thread in the body.
It will even repair slight damage.
Of course, it will not cut a thread in a completely stripped or overbored hole.
Please note that it is only suitable for the Dellorto DHLA and Dellorto DRLA versions that use mixture screws 9656 and 11068 as pictured below:
