15.5 Briggs and Straton on a craftsman rider fuel in oil

I just repaired the above lawnmower. I cleaned all the needle valves and finally got it running. Now it is running for about five minuites then blowing white smoke everywhere and dying. The engine is also blowing a combination of oil and gas out of the rubber tube on the air intake at the time of engine failure, and there is now gas in the oil system. Any ideas what is wrong with this thing?
