OK. On this on diagram on the carb it has vaccum ports with the following abbreviations:
C
BV
TCP
PV
T
Now the "T" port shows it is for the vaccum advance on the distributor. That is easy.
I was also just told the the "C" meanc, constant vaccum.
I need help with the rest.

 

BV=Bowl Vent, TCP=Temperature Compensated (Accelerator) Pump, PV=Ported Vacuum, It doesn`t show C or T in my vacuum manual.

 

OK. This is a start. Does anyone know what would hook up to the TCP port and the PV port?
