If how you described you unit is true you do not have an electric mower you have a gas powered mower, you DO NOT have a battery!!!??? Place the throttle lever to choke position and prime carb with primer bulb 3-5 times then pull cord. Wala!!!! It's running rite. That guy at Loews must have been smokin somthin. Good Luck...

you need to replace the needle and seat as the fuel we burn now damages the rubber so it doesn't seal

remove the top cover from the engine and see if theres a nest stopping the governor from moving

may have broke crank newer mowers are not built as they use to be take out plug and place finger over hole to test for compression if none u broke more than likely the crank

Does the plug itself falls off the engine or is it the wire that attaches to the plug? If it is the wire, check the rubber cap to make sure there is nothing jammed in there to keep it from seating on the end of the spark plug. The cap should snap into place when you press it onto the plug. If it does not snap on you will need to determine why. Inside the rubber cap there is a metal piece that fits over the end of the plug. If it is too big close it, some with a pair of pliers, if it is too small open it some with a screwdriver.

With the engine cold, check the oil level. Oil level is quite important especially in a smaller engine. Try to clean all excess oil off engine and body. Then, if you can get it running....check for any leaks. If it is still smoking, it has other issues besides being too full of oil. The oil breather will be full of oil. The oil filter may be saturated with oil. Check those 2 things especially as they allow motor oil to be drawn into the carburetor and cause excessive smoking. Pull out and clean the spark plug. Post back if needed.

BRIGGS ENGINE, USE SAE30 MOTOR OIL.

the easiest way is to run it out of gas and turn the mower on its side with the dip stick tube on the lower side and drain it from the dip stick tube
