vacuum gauge to solve idle issue

4spdragtop said
Dar the 4295S is on there now. See pic, hose is running to pass side port, which I believe is timed vac port. Correct? You can see dist vac can hose beside it (red plug in it)
When the eddy was on there, vac can was hooked to same.port (pass side)

OK, but which port are you hooking your vacuum gauge to....hopefully not the ported one for the distributor (finger pointing). If so, that may be why you're only getting 3 in. of vacuum at idle on your gauge.
