Engine vac lines
Is there a vac line kit for all the lines around the carb? Or are those the heater and light lines? Chasing a rough idle and with 41 yr old vac lines I figure they are a good place to start.

I was having same issue. After I capped the main line going to headlights it improved. Headlights were and are working pretty good still changing and inspecting lines in that system.

I just went through this with my 72 and it turned out to be a vacuum leak in the brake booster . Mine was such a small leak that it was hard to detect and the brakes seemed to work fine but with the new booster the brake booster is twice as sensitive and takes very little effort to stop . Isolate one section at a time and test for leaks .
