Try pulling out the choke a little, if it stops backfiring the mixture is too lean, check the intake
pipes at the cyl head and also the plastic runners to the carb for leaks.

First thing to do is pull your dipstick and check for broken or missing O-ring also as you pull it, look to make certain that it was seated properly and all the way locked. If either condition exists, you will be leaking into the crankcase which will cause your symptoms

You will need to replace or clean the air filter, and probably the spark plug. Do not operate the mower for some hours to allow the oil drain (inside the engine). Check oil level and fill it if necessary. Some oil remaining in the exhaust should be burnt next time the lawnmower operates.You will see smoke at the beginning, that will be normal (burnt oil). Hope this helps!
