The Stovebolt Site Forums The Shop Area Engine Shop vacuum advance plumbing on a 1946/47 216 engine

How was the vacuum advance "plumbing" routed on a 1946/47 217 engine routed - where was the fitting for the intake/carburetor vacuum source?

Photos would be appreciated.

Thanks

Hope this answers your question. There is a clamp holding the line to the top/side of the thermostat housing.
The vacuum line connects into the backside of the carb base.

Thanks Harold.

Is the vacuum fitting on the carburetor pressed into the carburetor, or screwed into a threaded hole in the carburetor/base?

Thanks

Harold,
The idle mixture screw is located right about this line, correct?

Do you have an image of screw B- idle speed adjustment screw?

It is a threaded connection on the W-1 carb. You can see this connection in this photo.

Andy, This is the best photo I have showing screw "B".

Harold is it the one directly on the linkage mechanism?

Is this correct?:

Andy,
Yes, the mark up in the photo of "B' is correct.
