 Hello Ted:

 This Sounds like the Carburetor Wasn't Cleaned Properly. However, if the Manifold is Cracked or there is a Gasket Leaking, this will Happen. What is the Compression? Is the Head Gasket Leaking? You can View a Breakdown/IPL at this Addy http://shop.briggsandstratton.com/BShopProductListingPage.asp?rsvp=0&PARENTID=0& and Enter the Model Numbers 402437 and the Type Numbers 0696 and Click Search. Then Scroll Down to the 2nd Listing and Click View PDF. This will Download the Breakdown/IPL of the Engine. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks. Be Safe.

 Good Luck
