[AT] 430V update

Sat Nov 25 06:11:45 PST 2017

I got Home late from family celebrations last night. The service manual was waiting on the front porch.  This morning I checked into the things I needed to find out. I have not found them yet.  The manual appears to be a summarization of what's new and different about the 420/430. It makes many references to the original model 40 manual. The governor/throttle linkage section is one of them :-(. The manifold bolts are not in the torque specifications list either.

Still looking in case I missed them...

However I did find one thing and I need to give some points away to Cecil.  As he suggested it might be, the  John Deere 430 is also a tractor that is timed at fast idle.  It runs smooth at fast idle and I have a great electronic tach to confirm fast idle speed so I'll get the timing easy as pie after reassembly.
