Carburetor control
 

Hello everyone,

does anyone know this nice part and can please tell me the outside diameter?
Thanks in advance!

I've seen those in books on Model A accessories, but I've never seen one on a car. I think it is only a label to fit around your GAV.

I'm curious, why are you looking for dimensions? Are you going to try an make one?

Guten Morgen!

You're right. I certainly don't need it to drive. But I like it as an past accessory and therefore I want to build it by myself.

Maybe try and search for a patent.

Werner, I doubt anybody who looks at your car will ever have seen one. If you make it so that it looks reasonable, who is going to argue?

Re: Carburetor control
 

Maybe you could measure off the photo since the knob is a known value. It is probably just a rubber grommet with a lettered face.

That's pretty neat, Werner. It appears to be stepped so it will hold the choke at the proper opening for "Start", "Warm" and "Run".

I like old accessories like this also.

Hi Werner,
Measure the diameter of a real GAV knob. Measure the diameter of the GAV knob in the picture. Compare the two diameters and note the difference. Measure the diameter of the accessory in the picture. Add or subtract the difference in GAV diameters to your measurement of the accessory's diameter. Looking at the picture, I guess that the diameter of the accessory is larger the the GAV knob.

Guten Abend.

Ruth, I made it easier to be flexible. I didn't make guessers twisted with the aperture. The cover is rigidly mounted and only the nose of the fuel adjustment points at the scale.

Bob, I appreciated that. It was not possible to compare because the picture is not a correct drawing, it was painted. But my dimensions fit reasonably well; the adjustment knob is approximately 0.9" and the cork 1.2".


I thank everyone for their comments!

Re: Carburetor control
 

We do this in industry but turn it into a basic algebra equation instead. Use the image measurement to real part measurement to find the size ratio and multiply that ratio by any other image measurement to get it's real life size. It's surprisingly accurate as long as your image is in plan or profile layout. Obliques don't do so well :)

Re: Carburetor control
 

I think that "Ruth" got it right... Look close at the photo, the housing is stepped. This device controls the "in and out" of the choke rod in two measures steps, full out "start" , half out "warm". then released for "run"

Yes that's right, Joe and Ruth. I misunderstood the function originally.

I thought it was a scale for the gas needle valve. As a reminder marker.

However, that are only different locking steps for the choke flap. Unnecessary.

I never need them in summer and I never drive in the winter time.
