You have two different issues here. 1)low compression 2) low vacuum.

A mistimed cam could cause the vacuum.

Try another intake manifold, it may be damaged underneath. I don't rember if the iron 4v has iron plugs in the underbelly?

Low compression is low compression.

Sorry best I can do from NY in the snow. Guess I'm gonna have to catch a flight to HI and drop in? Smiler
