[AT] 430V update

[Dean VP]

Patience Spencer. Patience... Rome wasn't built in a day. Put the magic
potion back in the cylinder and do something else for a month or so. My 60
Cylinder looked pretty ugly too but I didn't take the engine apart. The easy
thing to do is take the engine apart but then you will still have to bust
the piston loose. Might as well let it soak for a while and make it easier
for yourself now and even possibly later.  Right now all you have to replace
is the pipe flange but that can come later if stored inside.    Maybe you
can get lucky and not have to spend all the money on a complete overhaul
Gaskets alone are even expensive.   BTW, if you really want to get some
torque on the engine you can split the tractor. Not that big a deal and that
will give you a chance to check out the clutch assembly and the throw out
bearing. I split  it, put in a new clutch, new rear main seal and
reassembled my JD 320 in less than a day. Just a few inexpensive pipe O ring
gaskets are needed.

It's better to be judged by 12 than carried by 6.

I used Father's Day as an excuse to spend the morning working on the 430
instead of other things. I sucked out the penetrating fluid from the number
one cylinder (with my mighty vac vacuum, another handy use for it).  And
then got my inspection camera in the bore and found what appeared to be
typical water infiltration. Wasn't any signs of damage, debris or anything
like that.

But I was a little mystified. The muffler was on tight, no signs of rust in
the muffler or piping and no signs there could be infiltration anywhere
else.  No water in the oil or oil in the coolant.  There didn't appear to be
any reason for the water at all. And then I found this.   Any water that ran
down the muffler or ran off the hood into the exhaust pipe hole would have
gotten through this rusted out spot in the manifold flange.

Mystery solved but the bore looked pretty rough.   The camera isn't perfect
but I could see enough to see it wasn't just a little surface rust. 

I'm going to pull the manifold and head and pan.   I don't think force is
the right thing for this situation.  Rings are bound to be stuck bad.
