[AT] Drawn out 1949 AC-B engine rebuild

[Mogrits]

About 10 yrs ago my B became very hard to start and just as hard to keep
running. A compression test revealed...that it had almost none!

So one weekend while a cousin was visiting we tore down the tractor and
engine and found we could rock the pistons in the cylinders by hand.
Obviously the pistons, rings or sleeves or all the above were very worn. I
bagged all the bolts and photo-documented it all and still have all the
parts neatly arranged but have not touched it in that time. I need to get
off my butt and get that tractor back in the field.

What are the lists recommendations as to how to proceed? I purchased
Spencers book on engine rebuilding and read it years ago, but it is still
outside my wheelhouse as to what is necessary and what isn't. What do I
check in the crank and what will need to be done there based on those
findings? Head/valve work while it's apart?

I'm asking for the kick in the pants that I've missed since George Willer
passed.

(BTW, this tractor has no ignition issues as the magneto was very
professionally rebuilt by the now passed list member/magneto whisperer
whose name I can't recall) He was an extremely kind and funny man. When he
returned the rebuilt magneto he warned me not to park the tractor outside
as an errant breeze might move the tractor enough to generate a spark!
