SU carburetor choke clip for Austin Healey Sprite or MG Midget

If you don't have a locking choke knob on your Austin Healey Sprite, or MG Midget, or other vintage car using this arrangement, you might be using a clothespin to hold the choke in position. This simple clip is slightly more elegant. One end is 10mm thick, the other is 7mm, designed simply to increase the idle speed.
