A question came up elsewhere about how the vacuum lines work together on an engine with Strombergs.  The shop manual doesn't really show this, so I created a simple sketch.

Hi Mark,
Thanks for creating this schematic.

My question is what are the consequences of simply plugging off all these vacuum lines at the carb ? I have already converted the distributor to a non-vacuum assisted version and removed the carbon canister.

It would seem these are purely for emissions purposes and could be eliminated.

I'm sorry to inform you that Mark Rosenbaum has passed away.

I don't know how removing all the vacuum lines would affect the performance of the engine.

I have removed most of the vacuum lines and plugged them off leaving only the inlet manifold to the brake booster, plus I blank off the by-pass valve on the side of the carbs and adjust the temperature compensator so that it does not move and seals that chamber as well. Having done that and driven the car thousands of miles and done the same for a few other cars all I can say is it works for me.

Thanks for the info Brett. That is what I was looking for.
