Generally, Weber kits come with a little tab that goes on one of the exhaust manifold nuts, with a return spring to hang onto it. While it sort of works, it looks cheesy and often hangs up on other things and blocks access to the linkage and idle settings.
Here is what I came up with. (Pictured here is a DFEV, which is just a mirror image of a DGEV, mounted on a late Midget. A DGxV will be exactly the same, just reversed.)
I salvage the little arm and spring off of the factory Stromberg linkage and drill a 1/4" hole in the Weber cable bracket. Perfect geometry, clean and out of the way.
