Engine Storage
Gee whiz....
All the holy Wars over "to after run or not" is nerve-wracking.
If you don't care if your engine rots...neither do I.
For the rest....
At the end of a flying season....
Remove your engine from the model.
Remove the carburetor, back plate and glow plug. (Valve cover if applicable)
If there are plastic parts/pumps that remain...remove them or DISREGARD the following.
* Submerge the engine in KEROSENE (not gasoline) and turn it over a few times to circulate the kero throughout the insides.
* Remove the engine...shake out the excess kero and wipe the engine gently with a paper towel.
* Reasssmble, and place the engine in a sealed plastic bag.
* Your engine is now thoroughly purged of moisture and fuel residue, is coated completely with a thin oil, and is ready for the next flying season...whether that is next year, or 10 years from now.
