Hi All,
My question is regarding the correct vacuum hose routing for a single diaphram distributor. The correct hose routing according to a vacuum diagram I found for my year and model (1983 3.8 V6 CA car) is a hose from the "S" port of the carb, to a "VACVV" on the air cleaner (see pictures), then from there to the vacuum port on the distributor.
Here's the rub: With this set up I do not get proper advance after 3K rpm. I lose vacuum and power. If I connect the distributor directly to the "S" port I get full advance and vaccum at higher RPMS ( in other words, the engine runs like a champ with this set up).
What is that VACVV for (emissions related I figure) and how does everone else set thier distributor up? Factory of modified?
