Briggs and Stratton engine

Hi i have a briggs and Stratton engine model# 313777 type- 0112E1 16.5 HP and last year it died on me, started smoking really badly where it would just choke itself out and die, i replaced the needle in the carb and it worked a little better but still smoke but it ran so i used it, well now it just got progressively worse where it would smoke alot worse and choke itself out again so now i have gas in my oil, tried changing it and it just came back and it wont start, when it did start i noticed the gas and oil mixture pour out of the breather tube in the air filter housing and then choke the engine out, so at this point the engine wont even start, do i need a rebuild?

Just change the oil and put a float and float valve in the carburetor - the pair is less than $10.00.

Make sure you change the oil, though. It wouldn't hurt to change it a second time after you see you have it fixed. It's cheap insurance you have all the gas out of the oil.

check the float to make sure it actually does float.

OK so now we know that the float does float.
Using a Q-tip sparyed with carb cleaner, clean the needle tip and clean the seat.
Also, make sure the fuel solenoid (located on the bottom of the carb) is working. With the solenoid out, ground the threaded end, plug in the plug and turn the key on and watch the plunger on the end of the solenoid. With no power to the solenoid, the plunger should be out. when powered, the plunger should pull back in.
This shuts off the gas when engine is not running.
This could be your problem. Solenoid not shutting off.
And while you have the solenoid out and the Q-tips, clean the seat for the solenoid plunger.
Also, make sure the choke is fully opening and not sticking at 3/4 open.

If gas is getting in the oil, it is because the needle isn't seating in the seat. Clean the seat area well as indy mentioned. Take care to not put a scratch on the seat anywhere. Don't worry about the solenoid, it cannot cause the problem you're having and it sounds like it's working fine.
