[AT] Case 400 Diesel

[Mike Sloane]

That is the first time I have ever had that happen: the first part of my 
message was chopped off. It should have read:

"I don't know, Ken, if it were mine, I would try to get my hands on a 
service manual, take things somewhat apart enough to get some air in 
there, and see if maybe it can be run."

It was there when it left here...
