Endless Band Hose Clamp with Buckle - 5 mm wide.

This way, you have roughly a foot (or 33 cm) of band per clamp / buckle which is more than enough for regular applications.
Thanks to the generous length of band, there is virtually no limit to the diameter or circumference of the clamp that you wish to apply although these were usually applied to small diameter fuel lines.
Please note that this style of clamping is NOT suitable for steel-braided lines.

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
