Hot Rods Heres something you dont see every day. nos stromberg 97

Bought this at a swap meet. Think i paid $100 for it. It was still taped shut.

 

It was your day to get the brass ring. Did anyone notice in the Installograph that the circle that shows parts 12, and 13 that the kicker arm is shown backwards where the idle screw attaches ?

 

Mmmmmmmm , Smell that "Factory Air"
What a Find !

 

Very nice!

25 years ago I attended an auction at a small town NAPA store going out of business. I was able to buy an ancient rebuilt 97 in the box. Not NOS, but as close as I'll ever come.

 

Wow! Hey I don't have that spring on my chokes, what does it do? Are they all supposed to have it?

 

The spring opens and closes the choke.

 

For a brand new carburetor out of the box I’d have to say…. What???
Here’s your sign

 

OK, really that stupid a question? I asked because mine has no spring. I'm now home for a closer look. First off, the linkage is obviously different looking at it from the side. I see where the one tab in front would take a spring but not the other side. Also, the two pieces that would move by the spring are welded together (hard to see in the photo).

Mine is an original (not reproduction) that has been on a hot rod for many years, good chance somebody modified it, why I don't know, seems to work fine. I would like to know what the spring mechanism does, beside opening and closing the choke, I got that now.

 

Congratulations! That is a find. HRP

 

I had an identical one to that 97, box was trashed. I ended up selling it on here when I cleared out all my Stromberg stuff. Came from a customer that bought it for his 37 Ford when he was in HS

 

Fair enough, I had to take a quick look at my reproduction Strombergs from Clive and yes they have the springs.
From observing the operation of my choke and how it operates the throttle during choke operation I can see that it initiates a fast idle setting on the throttle for warmup.
When you open the choke the spring assists in cancelling the fast idle portion.

 

I'm guessing with the spring, under higher airflow the choke plate can be pulled open some to avoid overly rich part throttle operation while still on the choke. Just a guess but mine seems to suffer from that. When I take off from cold on the choke it goes fat and I have to adjust right away.

 

It seems to be a variable choke opening fast idle type of thing.
Works pretty well.
I can see how it would be a little bothersome without it but as long as it works why worry.

 

Wow, what a find, I predict you are going to be very popular around here, by the way, the Smithsonian called and they want your carburetor!

 

pffffftt............much ado over nothing..

Just kidding .....congratulations on your find!

That's one of those switchhitter models you install with base plate upsidedown

 

Love the printed information. Its not a set of Instructions. Its an Installograph. We used to have cool names for things, like Turbo-Rocket Fluid. Shame we have become more bland.
