Isn't that what it's for ?

The vacuum advance is just a rubber diaphram that connects to the points
plate and pulls it around as the vacuum on it's other side increases. It's
an economy thing not a performance thing and won't affect power, but yes it
should have vacuum up to the diaphram. disconnect teh hose at teh manifold
and with dizzy cap off give it a suck. the points plate should rotate a bit..

4 deg after should be too retarded, although I'm not familiar with those
weird american pollutions mods...
120-130 sounds low to me, that's about 6:1 compression isn't it....does it
smoke ? it could ahve no compression rings left but oil rings coked up and
thuis not letting oil past, does it blow seals in the engine ?

Why ? Nothing like remote diagnosis of an engine problem to get a really
good argument going :)
