timing vacuum barrel - you mean the vacuum mechanism on the dizzy? ok I think. When I accelerate the timing light shows the 2 max lines pretty quickly on the flywheel. So it does advance well.
What's the best way to check it?
(One of my friend's had just failed in fact on his newly restored sud Ti- he's looking for a replacement here)
When I set TDC advance yes I disconnect it (8 +-1 degree factory set), but then re-connect it to check at high revs.
At the moment it's 7 or maybe a little less at idle.
