The vacuum line to the distributor does not come from the nipple on the back of the throttle housing, which appears to have been blocked with something.
It comes from one of the nipples on the brake servo non-return value (the one which should feed the cold acceleration vacuum sensor, the other one is broken off with a screw stuffed in it UGH!)
Does anyone know whether not coming directly from the throttle housing would affect the sensitivity of the vacuum advance and therefore acceleration power.
Power develops rather slowly, although this could be just ignition timimg (set for 95 octane) or general old age (150k miles)

I was just interested to know whether a distributor advance/retard vacuum feed from the front of the inlet manifold ( i.e. the cold enrichment nipple on the non return valve) would make any difference from one taken the throttle housing. More or less sensitive to manifold pressure change for example.
If it made no difference, then I might not bother.

i think it could have an effect, tho i dont know why really, just strength of vacuum could be different. i think mines set up wrongly having looked at those pics, ill try it 2moro

Vac pipe from throttle body goes to the distrib for retarding/advancing.
Vac pipe from 1 of the connections on top (by rocker cover) goes to the MFA.
if there is 2 connections (usually is) block it off.
this is how my setup is, and to be knowledge correct.
