Mk2 vacuum issues?

[InsightMusic]

Hey everyone,

Can anyone tell me what the issue may be here: https://www.youtube.com/watch?v=S0TIyDVx2Lg

The vacuum lines are new and pretty tight. The engine runs smoother with the vacuum line out of the distributor, but once it's connected the engine becomes rather jumpy, dropping in revs quite badly.

The issue can be felt when in gear driving at low revs, making the ride very uncomfortable.

Any idea where the problem could lie?

I would say your ignition timing was out. try turning your distributor slightly with engine running and see if it smooths out. cant remember which way it turns to advance though.
