briggs 17.5hp blowback and other probs

Hi all ive looked through tons of articles and such trying to find an answer so hopefully someone here can help me out. i have a zero turn with a briggs and stratton 31g777-0115-e1 17.5hp ohv engine. ive replaced, carb, fuel pump, starter etc once i got it running it was blowing smoke heavily but no blowback or gas in the oil. now after all that i am still getting blowback into the oil and now gas. the engine also gets really hot after running for about a minute. im at a loss for figuring this out any help would be appreciated. i dont have any specialty tools or the ability to get them currently.
thanks for your time
pappa

You're getting gas in the oil? That's because of the carb. That is commonly a cause for smoking too, so I'm wondering if that isn't the whole problem. If not, it could be a blown head gasket, also a common cause of blowby and smoking on these engines.
