[AT] Cockshutt report

[Robert L. Holtzer]

My M had a problem with inadequate power and cutting out when I first 
purchased it.  Turned out to be sludge in the tank outlet/fuel filter 
inlet.  After cleaning the tank and filter I put a fine brass screen filter 
in the end of the filter so that it extended up into the tank an inch and a 
half or so.  It has run fine since.  I put similar a similar filter setup 
in my H after it stalled completely while attempting to unload from the 
trailer.
