Your engine should have a Nikki carb on it, if my books are correct. This book by Briggs 272144-6/04 covers the carb on your engine. Book is downloadable for free from Briggs.
This carb can be taken apart and cleaned or rebuilt. Although taking the carb off to clean it is not needed, but I recommend it. Much easier to work on.
Under where the fuel shut off solenoid screws into the carb you will find a selenoid seat (needs taken out gently) one out you will find what looks like a screw driver slot. Gently unscrew that screw and you will find an emulsion tube whth a bunch of holes in it. Make sure that the tube and holes are clean. (I highly recommend you have a carb rebuild kit on hand so you can replace the rubber parts).
On the top and rear of the carb, you should find a plastic cap that covers the Idle mixture screw, take the cap off and save or toss if you desire. The screws on the side are the throttle adjustment and throttle stop screws.
Using a can of spray carb cleaner spray into all the holes you find in the carb to clean them. Put the carb back together, adjust as needed and good luck. Carl
