long term storage

i have put the 23D back together after reringing it. it is a spare for my Big Ten, for that inevitable day when i will need it. i am missing a lot of the external stuff like flywheel, shrouds,muffler. when the time comes, i will canabilize from the old motor. so this one is going to sit on a shelf in the annex for many years, i hope. how should i protect/preserve this motor? i will fill it with oil and it will be wrapped in plastic but should i do anything else?

Fill it enough to submerge the rod bearing... lube the piston up really well, wipe the cylinder wall with oil, wrap it up in plastic, when it isnt humid out, and put it on the shelf-

Put the piston at the bottom of the stroke. Put a few drops of oil to lube the rings. I would then coat the cylinder with petroleum jelly. Then take it inside the house where humidity is low, and wrap and seal it in a plastic bag. It should then last for many years. I would recommend checking it every couple years till you determine the extent of rusting/corroding that is happening on the shelf.

I wouldn't wrap it in plastic at all. Seals up too tight and will collect moisture through condensation due to temperature changes. Then it will not allow the moisture to escape The only reason to cover it is to keep it clean. I'd lube the piston as suggested, set it on the shelf and cover it with a brown paper grocery bag. Just slip the bag over it, tuck the edges of the bag underneath and let it go at that. I would also use a good break in oil, or chainsaw bar oil to lube the piston as either is fairly sticky and should remain where you put it for much longer than regular engine oil.

If you do wrap it in plastic get some dessicant/silica gel bags (the little packets that come in sneakers & electronics that say DO NOT EAT) in with the engine. I believe you can get them at gun shops and online. That's what we do with aircraft engines when they are put in long term storage. They also make dessicant plugs that screw into the spark plug hole to absorb moisture in the cylinder. The nice thing on those is they change color when subjected to moisture. Here are some links I found and I'm sure there are tons more.

Dav, I would: oil it up, keep it clean, keep it dry (inside??), but definetly keep it where you turn it over on occasion, like once a month. Just be able to grab the crank & give it a twist. My 'piston count' is somewhere in the 20's and I have had very good luck keeping them alive by hand cranking them on a regular basis. John
