Vacuum questions 1987 4kCSq

[Bernie Strub]

The vacuum diaphragm on the distributor is a typical failure.  One symptom
is a loss of midrange power.  I have gotten replacements from Worldpac
dealers, I don't recall them being wildly expensive.  You will need to
remove the distributor to install the new advance canister.

Brendan sed:
2) The vaccuum diaphram on the ignition distributor does't seem to
hold any vacuum, normal or is it in need of replacement? My bet is on
the latter, so if that's the case and anyone has a good unit cheap let
me know.
