i use stabilizer in the fuel for the last 2 mowings, and when its ran for the last time i spray fogging oil down the carb until its smoking real good or stalls out, change the oil, sharpen blade, clean the deck undernath and spray down with WD-40. service the foam air cleaner element, take out the spark plug, turn the engine to top dead center, spray fogging oil into clyinder until coming out the top. put the plug back in and top off the fuel tank with stabilized fuel. come spring i take out the plug and spin the motor over a few times to blow out any excess oil, put in a new plug and its good to go. ive seen many problems due to not putting things up properly, its well worth the time to maintain equipment. the first fire-up is a smoky one, but it sits 6 months out of the year and for a 1985 briggs mower, its still as good as new operationel wise. i rarely have to do anything but add fuel during the summer when the mower is in use.
