I don't understand, unless you have a very old engine using an oil bath filter system, there should be NO oil in the air filter housing.
I would guess either the crankcase is full of gas/oil mix, and overflowed the engine, or this thing has been tipped over.
Try this. Remove the spark plug, and place a large rag in front of the spark plug hole. Ground the spark plug wire. Turn the engine over, try to start the engine. I'm guessing that the cylinder is filled with a gas oil mixture. You will see gas fill the rag. You ground the plug so there is no chance of a spark, as you are going to get a lot of fumes. After no more gas comes flying out, install the plug and change the oil. Then try starting the engine.

also ,I am guessing you dont feel like theres a problem with the starter or solenoid or key switch or the relays , since it is trying to turn the starter, and how would i test the starter to see if it is bad ? thanks !!!
