Hello List,

I'm looking for suggestions to solve a lack of power problem in my 90
Westy.

Symptoms:
------------
* idles okay @ 950 rpm, revs up and down smoothly in neutral (no load)
* when under load it bogs down with very little power
* happens in all gears, but particularly in 3rd and 4th gear
* engine vibrates (more than normal) when under load

Attempted fixes:
-------------------
* timing adjusted per Bentley
* changed AFM
* checked O2 sensor and voltage
* looked for vaccuum leaks and made fixes
* gas line not frozen, good gas
* changed Temp II sensor

Other:
--------------
* Compression is:
#1 (105)
#2 (135)
#3 (105)
#4 (135)
* Oil pressure is good.  Engine not burning oil.
* Exhaust seems to be free flowing okay.
* No rich running problems, no black smoke.
* The problem happened when driving on the highway.  I was pulled over
by the police and when I was accelerating hard into the highway
traffic the engine bogged down with the symptoms above.

Any suggestions would be appreciated.

- Laurence
