Couple truck problems at work years ago. 64 GMC 1 ton- very fast idle. Boss said "check it out'. Take off air cleaner to get at throttle linkage, idled right down, drove it around a bit, everything normal. Next morning after first load of freight uptown driver complained about same thing again. After 4 or 5 sessions of this, noticed scratches on bottom of air cleaner. First start in morning driver pulled the choke. When he pushed it back in, long tail on choke cable snagged on air cleaner, bent around, held choke partly closed & fast idle cam stayed on. Repair was to clip off excess end of cable. 64 IH truck tractor, 345 gas. When downshifting pulling a hill, the radio would cut out, finally couldn't move. Ran fine until try to start out, then die again. After calling for help discovered bad motor mount on left side. Torque roll starting out, or shifting pulling a hill, rolled motor to right, battery cable at starter hit frame, shorting everything out. To get moving wrapped leather glove around batt cable, then went to shop for motor mount replacement. MCI stagecoach, air operated aux step at door. Hit the switch it would extend part way & stop, but wouldn't retract from there either. Can't travel with step part way out. Mechanic found bad diaphram in control valve. Rebuilt valve, same thing. Replaced complete valve, still no change. Valve has 4 ports, supply, extend, retract, & exhaust (like return on hyd systems). I was scheduled to take that bus on a 15 day tour the next morning, so went to shop in evening to load my travel gear. Putting our heads together, found the problem. When the first valve failed, someone pinched off & tied the exhaust tube to stop the air leak & put a "do not use" tag on the switch. Open up the tube & everything normal. Willie

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
