That’s pretty cool! No water injection?

When I had a DCOE I used a choke cable from a 61 corvair, mounted under the dash. For what it's worth, the "cold start device" on a DCOE doesn't really work that well. It does not choke at all, just adds a little extra fuel and mine was always hard to start when cold, whether it was activated or not. It does help once the car starts to keep it running while warming up.

I never bothered hooking up the cold start enrichment circuit on mine, and just figured out the procedure for starting. Like Nate said, that circuit doesnt work that well anyways. The reason is that Webers are not really designed to be used on draw through turbo's, and the long distance between the carb and heads "mess's" with them. They really were designed to be mounted as close to the intake port as possible, and the aux venturi on those is designed with the pulsating/vibrating signal that is present when mounted close to an intake port. This special aux venturi is very rpm sensitive, not really "vacuum" sensitive, and is sorta geared around starting the main jet at 3000 rpm. The idle jets are supposed to be running the show up to 3000 rpm. This is not to say that you cant get them to work well on
a draw through turbo, far from it!

Thank you for all of the information! I live in the PNW and probably won't be driving the car in colder weather, but around here our summers can be similar to San Francisco (insert Mark Twain quote). So I think I'll wait on the choke cable for now. Much bigger fish to fry.

I feel that it actually helped start mine. The cable I used was whatever Clark's sells for the EM manual choke.
