Holley NH Carb question
Okay, I am a newbie, but does anyone have a photo of an installed Holley NH, later model with the universal joint type mixture adjustment on their car? Mine doesn't fit well and I have another (new) rod that is supposed to fit that carb. I just want to know if what I have is installed correctly. I am most concerned with the point where it connects to the mixture/choke rod.
Thanks!
This is mine that I am trying to get correct.

Re: Holley NH Carb question
The carb is pre 23. The throttle lever should be shorter.
The choke lever arms should also be shorter with an offset in 1 arm to clear the choke pull rod.
Fuel line routing is also wrong. Close to the manifold center.
The line runs straight down from the valve & 90 degree horizontal @ the inlet level.

Re: Holley NH Carb question
You will need to get a similar set screw choke wire anchor on the rod and position it so it does not interfere with the hot air pipe when you turn the mixture screw... After that's done, just simply measure for another connecting wire between the pull and the carburetor choke lever

Re: Holley NH Carb question
Hey, thank you. Do I need to redo the fuel line? I am a complete newbie and don't know what to do! Thank you!

Re: Holley NH Carb question
There was not a shaft collar originally. A cotter pin, as you have on the bottom is correct.
The pictured fuel line doesn't look correct either. The fuel line fittings are not correct.
The heat pipe (actually an accessory automatic choke) is also incorrect.
Don't use this picture if you want to be correct.
A correct pix will come along.

Re: Holley NH Carb question
OP asked to see what's "correct."
I provided a previous post with pictures of the correct carb & fuel line.
Do not use my fuel line connection as an example, It is not correct either.
The difference is, I know it.

Hi John, I absolutely love the manifold, dual carbs, vaporizer exhaust. What is that casting? Allan with all that going on you noticed the
cutout?

Re: Holley NH Carb question
Apparently Speedytinc doesn't know what a 1920 straight through NH carburetor looks like, neither a 1913 Ford aluminum intake. The aftermarket hot air pipe has two circular vanes inside to start swirling the intake air and the internal valve was removed so it is a straight-through pipe. The gas tubing is one size larger than Ford supplied and can easily be replaced as long as the curvatures are replicated from original..... And thanks goes out to Allan and Craig, also to Mark for posting his picture, appreciated.

The exhaust casting is a mystery part found on tbay.
Fits the hot plate pattern near perfect. no gasket. I speculated it was from a knight sleeve valve motor or tractor.
