Which of these two diagrams is correct...the top or bottom one?
The difference is the hoses at the dizzy vacuum can...they cannot both be right. [NOTE: I deleted the incorrect diagram originally posted...the diagram remaining is the correct configuration] Attached image(s)

I've worked on the 1.8s since BEFORE they were on the market (prepped some at the school, and replaced a head on one before we sold it) and there have been a couple here at the shop in the past month or 2. Both had dual vacuum, and one is a '75. I don't recall any without it. Later bus engines didn't have dual vacuum, but the timing procedure is different, too.
