Zenith banjo bolt needed

[milwaukeesk]

I wonder if anyone could help me out. I found a broken off bolt holding one of the thermovalves on one of my zenith carbs. It’s unique in that it allows for air flow.

If you happen to have a spare, please let me know what it’s worth to you. Equally, if you know where I can order one, any guidance would be helpful. Appreciate it!

i do not use those air thermovalves in my engine
shipping is expensive though
i would let local us members to say a word first
if you dont find it locally just let me know

What do you use in place of the thermovalve?

Thanks deQ! I updated my title with the appropriate name now, Agree also on shipping, let me see if I can track one down stateside. If not, i'll gladly take you up if you happen to find one.

i have no thermovalve

there were several zenith models,
i.e. 2800 cs has no solenoid valves
my 3.0 cs dated 1971 has solenoids, but not thermovalves

Are the solenoids mounted in the same location. My one Zenith has what is in the pic above, the other has something in the same location but is oblong in shape. This is a 72 Bavaria. I have no complaints, car runs great, just want to be educated. I always viewed these as an early cold start valve in non fuel injected cars.

These were a feature in US cars to reduce emissions by getting the car up to temp sooner. They are tied into the bimetallic strips in the water choke housings with green wires
