Remove carburetor, disassemble it, clean all internal parts with carb cleaner and blow out all ports with compressed air. Reassemble the carb with new float needle and bowl seal. Drain motor oil and replace with fresh oil. Since the oil had a quart of gasoline in it. I will change the oil again after 5 hours of use.

Pulled the air breather then pulled the carburetor. Disassembled the carburetor and cleaned it then made sure all the passages were clean and free of debris. Reassembled with new needle valve. Put the carburetor and breather back on and changed the oil. Changed the spark plug with the proper gap. I the set the air mixture screw at 1 full turn out from all the way screwed in and started the motor. I ended with adjusting the air mixture to 3/4 turn out. Runs great

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
