What is the correct vacuum reading from the port on the bottom of the log
manifold on the early series cars using the Zenith WIP carbs. My engine
is not stock and I have been trying to dial in the carbs. I have changed
my choke tubes to a larger size and have been able to drop the vacuum
reading to about 32". I suspect 22" is more appropriate. Does anyone
know the correct number or can anyone measure it for me?
