Why does the mower not start with plenty of gas and oil in it? It’s also leaking gas and has white smoke coming out the side. Update (05/20/2017) It was also leaking gas and had white smoke pouring out the left side. Update (05/21/2017) Here are some pictures of the mower in its current condition. Tried it today and it shut on for less than a minute then it shut off.
joannjones2k Is it possible you have over filled the oil. If you didn’t use the mower last year the carb cold be fouled with ethanol from the old fuel . Try removing all the fuel then putting fresh fuel in . Was there any knocking noises when the mower quit? How much gas leaks out and does it leak when its not running ? If its coming from the fuel line? It can be letting air into the fuel line and keeping it from running .Does this mower have a primer is it leaking fuel there? If its possible can you remove the spark plug and describe it using this chart. I will help farther if you answer these question
joannjones2k, If you have checked all what has been suggested so far, and it is oil being expelled, you can check/remove the oil filler tube and check it has a rubber O ring seal in place at the base of tube, to seal to the engine fill port. If all looks good, there is a chance that the engine assy. case bolts may be loose/gasket blown out or there could be a actual crack in the engine case. Some of these mowers had up to a 4 year warranty, most were 2 year, If you can check if under warranty and if able use the warranty to have mower repaired/replace/refund. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
Have you checked to see if there is a fuel shutoff valve? This could cause it to not get fuel flow to the cylinders.
