Hi All,

I want to get my idle mixture just right and wanted to do it with a vacuum gauge. Plus to see if there might be other issues (pretty good troubleshooting tips using a vacuum gauge here http://www.secondchancegarage.com/public/186.cfm). Anyone know where I can hook up a vacuum gauge without drilling any holes in the intake manifold? I don't see any vacuum access points on the carb or intake manifold and there isn't a PVC valve on this engine.

Thanks in advance.
