[V8] So far off topic that you simply can't believe it....

But I was wondering if anyone out there has any knowledge of Detroit 4-71
engines?

We have a forklift truck that has a Detroit 4-71 that has a peculiar and
very annoying problem:  it will not hold rpm on load.  It will idle like
fury, and when in neutral, will rev up to the very top...whatever "the VERY
top" really is.

But as soon as it gets load, it will just bog down to nothing.  The engine
still runs, but without enough power to move the fork truck out of its own
shadow, until eventually, VERY eventually, the engine will rev up enough to
move and rev some more, until it dies down again. All this with the throttle
mashed to the floorboards.

Any thoughts?  Fuel pump?  Governor?  I dunno....

For those of you who may not know (and probably don't care) the engine is a
two cycle diesel with supercharger.  It is four cylinders of the same type
that was used ad nauseum in old Greyhound busses in the sixties and
seventies.  The ones with huge oil smears all over the ass end.....
