 Are you sure it is the temperature and not just the voltage stabilizer?=C2=
=A0 Does the fuel gauge stay steady or does it go up at the same time?

Subject: [TR] Vacuum Advance of a delco remy

Listerati,

I=E2=80=99m trouble shooting a overheating problem at highway speeds (65-70=
mph) with my 69 Spitfire. Temp gage goes to red at higher speeds but then i=
mmediately cools off when idling.

I suspect I have a bad or weaken vacuum advance on my Spitfire=E2=80=99s de=
lco remy (friggin spell check made me type that over and over) distributor.=
 I tested the vacuum line from the carb and it gets to 9 psi where the line=
 connects to the vacuum advance when the engine is at 2500-3000 RPM.

The problem is there is no movement to advance the timing that I can see by=
 watching the vernier advance knob, it does not move at 2500-3000 rpm.

Two questions:

Should 9 psi be enough for the vacuum advance to work properly?=C2=A0 I cou=
ldn=E2=80=99t find specs for vacuum advances.

If the vernier knob isn=E2=80=99t moving then is the vacuum advance not wor=
king or the centrifugal weights not moving? Or maybe both?

Thanks
