My push lawnmower was smoking and quit running today. It has plenty of gas. I added oil too. What should I do?

Did it start smoking before or after you add oil? First check the oil level with the dip stick. If if is above the full mark drain some out. On most there is a plug on the bottom side of the engine. Remove the sparkplug wire and tip the mower, air filter up and remove the drain plug. There will be about a quart of oil. Put the plug back in and fill it to the full mark with new oil. Next remove and clean the air filter. If it is a paper filter and has oil on it replace it. Without the airfilter in place start the engine and let it run until the smoke clears up.My push lawnmower was smoking and quit running today. It has plenty of gas. I added oil too. What should I do?

First thing, Clean the spark plug.


If it was smoking , the plug is probably all coated with carbon.
I would put a new filter in it,or wash the one in there reallly good.sometimes you have water in the gas tank,you should drain it and let it dry out completely.Then fill.also replace sparkplug.
sounds like your burnt the rings i n the engine , and or you added too much oil, hence the smoke, but drain al lthe oil out of it ,and only put back in to the level , if he wont start , it mite be dead , may it rest in peace!! ,with the other 40 million law mowers this year lol lol
You let it run out of oil and it will never be as good.Scrap it.
Clean the carburator, that is usually the culprit in many cases.
You may have added too much oil, this could cause excessive smoking. If this is the case just remove some of the oil. If this does not fix the problem it is the piston rings and you need to take it to a small engine repair shop.
Sparkplug is bad...thats the good thing..the bad thing yor engine just committed suicide.
