Carb adjustment with vacuum guage

[brian.b]

Hey guys I'm getting ready to try and tune the carb on the 48 and was wondering where you hook up the guage I think the only vacuum port on my carb it to the vacuum advance.....can I un hook it and tune it or should I put a tee in the line some how

A vacuum gauge needs manifold vacuum.  Kaiser vacuum advances are normally hooked to carburator vacuum. Vacuum wipers use manifold vacuum. Manifold vacuum is present at any engine speed. Carburator vacuum is only present above idle, the higher the speed the stronger the vacuum.

And I'm an idiot...... ......I never though about the wiper vacuum thanks guys
