IMO @ 1/4 teaspoon in the plug hole and a teaspoon in the carb. Do the plug first and turn the engine over several times to circulate the oil before doing the carb and doing the same. Then put the plug back in. Try to make sure the engine bearings get coated well with oil, a big (.60) engine may need more oil. Wrap engine in plastic to keep dirt/dust out of it during storage.

In spring take out plug, cover head with a rag to catch spray and turn engine over with starter to flush cylinder, check plug and reinstall. Checking plug will also burn off any oil residue. Always turn engine over by hand the first time to make sure it turns free and that you will not damage engine with the starter
