1984 Vanagon with new (rebuilt) engine with less than 30K on it.  Two years
old.  Compression on number 4 has dropped to about 60 pounds when cold.  Run
the engine for 15-20 seconds and recheck and the pressure is up to almost 90
pounds.  Sounds like valves but all of the mechanics say it is the rings.

Also having a cold starting problem.  Seems that the enrichment is not
working for cold starting.  Have checked temp II sensor and it seems fine.
Have to recheck the temp I sensor to see if I measured it right.  Then check
the wiring for opens to the control unit.  Any ideas beyond that?
