OT: Long term storage of small gas engine

Drain the carb, if its an IC, put 2 spoons of oil in the cyl. If its got a metal gas tank mounted to it, make sure its drained as well, I pour 1 cup of oil in the tank and turn the engine all around coating the inside of the tank. have had them sit like that for years, change oil, add gas, and they fire right up.
 
Carb must be dry. Best to empty the tank as well, but you can always dump the tank later. I like to to take out the plug and dump a little Marvel Mystery Oil in the cylinder, then turn it over a few times.

Very important: After the plug is back in, turn the engine over until you feel compression. Closing the valves does two things: It keeps moisture out of the combustion chamber, but it also helps to prevent the valves from sticking open.
 
Make certain entire fuel system is 100% full of 100 low lead.
Fill the crankcase with fresh oil. Squirt several snorts of oil all around through the spark plug hole while slowly turning the engine.
 
Run engine until warm, shutoff and drain gas tank, then fill gas tank with diesel fuel, start engine and let diesel get into carb and finally foul plug to stop. This will coat valve stems, cylinder walls with light oil, some will get into crankcase. When you want to start it again, change engine oil, drain fuel tank and replace with fresh gas, drain carb float bowl, new spark plug and crank a few times. On small engines using diesel you might have a couple gaskets and seals that might be suscepible to swelling from the diesel. This is relatively quick way for storage prep, was used a few times for motorcycles that got caught in first storm of winter and needed to be parked in back yard or corn crib corridor with tarp, some garden tractors. Smoke a little but most of them I knew about got on road quick next spring or 2+ years later when owner got out of service (or prison in couple cases). RN
