Small Engines (Lawn Mowers, etc.): GX160 QX2 Will not fire

Question
I have a couple of gx160's i acquired from a friend. What i was wondering is, I have gas going to the engine, I have fire going to the engine, but it will not even act as if wants to start up. I tried pulling the oil sensor plug into, it still will not hit on anything. I was wondering if you had any ideas on what could cause this problem or if you could direct me into a couple of things that could cause this?

If you have fuel and spark to the engine and it wont start or even act like it wants to start you may have a carburetor problem. There may not be enough air going to the carb. Try spraying some carb cleaner in the carb intake. If it starts then shuts down then rebuild your carburetor.also check the low oil sensor that will prevent the engine from starting.
