[AT] Cockshutt report

Ralph,
    Is the vent open in the fuel tank cap?  Sounds like it could be drawing a vacuum in the tank.

  The wind finally let up on the weekend so even though it was still -20 by
  day it still felt relatively comfortable working outside. I fired up the 50
  yesterday to run a few bales through the hammer mill and it worked great. No
  sign of any damage from its running short of oil in the valve train for who
  knows how long. I'm doing a coolant flush on it now. Seems to be a lot of
  sludge in the block on this tractor.
  The 40 was not quite so successful. I changed the suspect coil to see if it
  would cure the cutting out problem under load. I'd have to say it made no
  difference at all. Tractor still started up good but would not keep running
  without choke until I adjusted the load needle on the carb again. After a
  long warm up I tried some snow blowing. It ran good for about 5 minutes and
  then began cutting out every time I got the snow blower running full. Choke
  helped but too much would cut the rpm while not enough just let the engine
  die. A couple of times I was too slow on the chke button and the engine did
  die. Heres where it gets interesting. After the engine re-starts it will
  work good for a few minutes until it seemingly runs short of fuel again and
  I have to go through the same choking procedure.
  I managed to get the driveway cleared and re-parked the tractor in the shed
  in hopes of trying a different carburetor. I did find the spare Zenith
  carburetor but I'll have to take it apart to check it out for missing parts
  or other problems.
