Gas was leaking into the oil crankcase
I noticed a small puddle on the floor. It was oil and gas mixed. Then I checked the oil level on the dipstick and it was way over full and smelled like gas. After some research I found out that the Briggs & Stratton engines (mine is a 18hp Intec) are known for the needle valve in the carburetor to go bad. The reason is that the tip of the brass valve is rubber to make the seal. Also make sure you replace the seat that the needle valve goes into because it will be worn too. A 1/4" tap fits perfectly into the seat. thread it down (carefully) and stop as soon as you feel it bottom out. I used a 5/16 socket that I drilled out so the 1/4 - 20 x 1 1/2 bolt would fit through it. Then sit the 5/16 socket over the seat and place a washer on the 1/4-20 bolt and thread into the old seat. This works as a puller and will lift the old seat out. Note: check the old seat before pulling it out to see how much protrudes out of the hole. To install the new one put a little oil on it and place it straight in the hole and use that same 1/4 - 20 bolt with a nut on the end now to drive it into the hole. Don't forget to make it the same protruding out as the old one. Reassemble the bowl on the carburetor and your done. Take your time and the repair will go pretty easy.

the motor was flooding
I removed the intake and carburetor it was easier to do that instead of just removing the carburetor. i then removed the carburetor bowl. i took out the float and needle. I used the 1/4" tap to make threads in the seat and then used the screw washer and tubing to make a puller to remove the seat. I then replace the seat put in all back together and now the mower runs like new again.THANKS
