Kieth,
Go to your nearest A&P school and get a copy of the "43-13". this is a manual of std practices as approved by the FAA. In it I think you will find the info on how to preseve your Shaky Jake. my copy is at work. I will look at it tomorrow and update. As I remember it, the proscess involves a special presevitive
oil, plastic inserts in the sparkplug holes that are filled with "desicant" material (moisture absorbing material) , and finally sealed in a bag which has several cloth bags filled with desicant.
Take the time to learn how to do it right.
BTW That is the very first aircraft engine I ever built. It is amazing. we tore one down and built it back up for a school project.....keep in mind this eng had been messed with by countless students.(including people's initials carved in the piston domes) we hung it in the test cell and fired it up. It was just awesome to see the fire billow out the collector ring as she spuddered and coughed to life. (no sound compares to a cold radial struggling to start) As old and abused as that engine was, it still pulled rated manifold pressure!!!
The generation of people that designed those engines was a very special breed. There will allways be a special place in my heart for that beast.
