control connection block and carburetor control rod question

[Tommo]

Here's one for you guys.
From 1925 to 1928 the HD Parts Manual lists a Zenith carb.
I've never seen one either fitted or in the flesh.
Has anyone ever seen one fitted to a Harley or does someone have one?
How would your Judges react if someone turned up for judging with one fitted?

Schebler introduced the De Luxe carb in the late spring of 1922. There's an announcement in the May Motorcycle Illustrated. It's interesting that the 1 1/4" was available first; the 1" a few weeks later.

Bob!

So we just ignore the Service Station Manual, etc.?

I can do that.

PS: Tommo!
The only Zeniths I've held in my hands were for Hens.
They were diabolical.

I've been studying that front control coil bracket, specifically those two nuts. one is larger across the flats than the other and that same nut is also thicker. I understand why they cannot be small like the ones typically used.

On the rear part of the bracket, I THINK i understand that these two nuts tighten on the control coil against each side of the bracket....? is my understanding correct?

i guess my question is how those 2 nuts on the front part of the bracket are held in place...... Same as the two nuts on rear part of bracket, by the control coil coming from handlebar throttle control? (Obviously in the picture there is no control coil, or is there just a short piece of control coil to hold those two nuts in place?)

i am guessing those nuts are special and have the same thread as the control coil. I would imagine these nuts are also rare as hen's teeth and i'm thinking will need to be made up by using the small nuts to fabricate the larger nuts. On a long shot, does anyone have two thin and two thick nuts available........?

Steve, One of the nuts you are referring to is like a short bolt that has an internal thread that matches the cable and external threads that a nut goes onto. It threads on to the cable, then goes into the bracket and a nut goes on the external thread to lock in place. I hope I'm making this clear.

Thanks John. Thanks for the explanation, I understand now. a special little critter. They're made of unobtanium and impossibillium. is the rear one like that also?
