I have a 2 year old Toro push lawn mower that will not start. Everything has been tried: new plug, new gas, new air filter, even tried starter fluid. There is not even a sputter.

because it's a "push" mower... lol, get it... ok let's move on. Dirty air filter and/or spark plug, bad gas, dirty carb, no spark blown engine. operator presence handle not working correctly...
First check the gas. Old gas after only 3 or 4 months of storage will not fire properly. Completely drain the tank and add some fresh gas. Also take the air cleaner off and check the air filter. It is possible you may have tipped the mower to that side while hosing the grass from the underside. The filter could now be plugged with oil and the motor can not breath. Replace the filter if this is the case. And finally, replace the gasket on the back side of the air cleaner plastic housing that attaches to the carburetor. This gasket if defective or dried out can prevent the primer bulb from injecting gas into the carb when you pump it. Its also possible it fell off if you ever removed this cover which is bolted on with 2 screws. Some dealers even go as far as to put 2 gaskets on to get a good prime. If these simple fixes don't work. You also could have sheared the key way when the motor hit something you ran over in your yard. That will require a shop to pull the flywheel and gets a little more involved.
Battery required? Charge battery or replace. Replace air filter and spark plug. Dump out old oil and replace with 30w oil. Electric start may have a fuse blown. Dump out old gas fill with new with Stabile always added to gas. Try spraying starter spray in carb at air cleaner with filter removed. All mowers have a low oil sensor to prevent starting on low oil. Remove bowl from carb, should be full of gas. Pinch off fuel line with pliers or turn fuel valve off. Check float should be hanging down allowing fuel flow. Float up stops fuel flow.
Remove spark plug and observe condition. Fouled with oil, bad motor. With plug removed pull rope several times to blow out cylinder. Spray WD40 in spark plug hole, pull rope several times see if oil blows out. Spray a lot of starter fluid in spark plug hole, replace plug. Spray starter fluid in air cleaner area of carb, try to start. Replace spark plug, try to start. Ensure oil is full, all mowers have a low oil sensor now. 30w oil. Always use Stabile in gas.
what is the model, manufacturer and year of mower?
has any maintenance been performed on this mower?
if no, try replacing the spark plug and air filter (it's possible the spark plug could be fouled and/or the air filter is clogged) be sure to follow the manufacturers recommendations for oil, gas, filters and plugs.
The problem is that the gas that sat in the carb all winter glazed it over and gummed it up. Begin by going to any auto parts store, like an aiutozone, and getting a bottle of carb. cleaner. Seafoam is one I use. Add it to your gas, one ounce per gallon of gas. Also, pick up a can of engine starting spray.
Remove the air filter and spray the engine starting spray into the air intake. Pull start the engine and give it additional squirts of engine starting spray until it runs smoothly.
