Oil in thew air box, if it cam from the engine is a sign of wear. Do a compression test to see if the engine isn't worn, and if you can, look at the valve .(If it's four stroke)

Have you checked for spark? That's where you need to go to first. Take out the plug, put it back on the plug wire and hold it against the cylinder head. Kick over the motor and watch for spark.
Not a big deal. Im assuming this is a 4-stroke push mower and not a leaf blower. Remove the air box cover, air filter, and air box back plate. Careful there is a gasket on the back of the backplate that if damaged the primer bulb wont work, part # 272653. Remove the fuel line from the carb and drain the tank. Using a 1/2 inch wrench remove the bowl nut from the float bowl on the carb, hold the bowl to the carb as to not break the gasket seal, drain the bowl and replace the bowl nut. If you tried to run the unit and oil is in the cylinder remove the spark plug ( clean the spark plug) and spray some carb cleaner in the hole and pull the starter rope several times to purge the cylinder. Reinstall the spark plug, reattatch the fuel line, install the air box back plate ( leave the air filter and cover off for now), add fresh fuel. Take unit outside and start, you may need to give it a shot of carb cleaner in the throat of the carb to help it start. It may smoke, it may blow oil out the muffler. Let it run until it quits smoking ( usually around 5 minutes) . Shut it off and complete assembly. It should be fine.
Remove the plug and reconnect the coil pack to see if it has a good bright spark. If yes, do a compression test. If you are at least over 100 psi,see that your carb is clean, and not gummed up with old fuel.
Sounds like the carb has over flowed and filled the crankcase with gas. You will need to drain the oil, and re-fill it with new oil at the proper amount. Also replace the oil filter. Clean the air filter and replace the spark plug. Clean the carb, making sure the float and float needle are functioning properly. That should fix you up! RSRBOB
if it has a kill switch make sure it is on, check that you are getting spark at the plug and have the right fuel in the motor.
Remove the air filter from the carbi and squirt some 2 stroke fuel directly into the throat of the carbi and try to start it.
hope this helps
i have a 04 yfz 450 quad. the compression ratio like yours is extremely high. ive had my battery go bad and found that another battery other than factory would turn over the engine, but would not start. i paid the 100 dollars for the factory battery and it fired right up. because of the high compression you need a high cranking battery.
