I'm about 75% of the way through this, and when trying to loosen some of the fuel lines from the distributor, the entire fuel mixture unit tilts up at the rear and rocks towards the firewall. Maybe there's nothing wrong with that, but it seems like the W-pipe should be removed AFTER the fuel lines are disconnected, to hold the mixture unit more firmly in place. Is the rocking anything to worry about? It's pretty bad with the horizontal banjo bolts, and no assistant to hold the mixture unit in place.
