When I rebuilt the engine from my '81, I had compression something
like 90-100-110-120.  The van did not smoke, the plugs didn't get
fouled, but I burned about a half-quart of oil per tank of gas.
The tailpipe was always black.

After the rebuild I feel like I gained some power, 10-20% or so,
and of course no oil burning.  I seem to have created a new two-drop-
per-day oil leak, sigh, but otherwise it's great.  Mileage went from
maybe 16 on the highway to 20.  Tailpipe is still always black,
although not quite _as_ black.  I only drive in town, pretty much.

I doubt that this is much help, but it's all I can offer you.  I
don't recall what your compression test gave you, but if you're
having a _major_ loss of power, I supsect it's somewhere in the
FI, electronic or vacuum.  Then again, I'm no expert!
