QuestionI have gas getting into the crankcase. I have rebuilt the carb but still get
flooding mainly when engine is off. I notice the rubber seat is loose in the
brass seat and will fall out of the brass seat easily.
1) Should the rubber seat fit tight in the brass seat?
2) Can the brass seat be replace on this carb?
3) How is the brass seat replaced?

Model 190707
Type 2518-01

AnswerHello RKH:
Sorry for the Delay. This Question was Located in the Question Pool. From your Description and From Viewing the Breakdown of this Engine and Carburetor it Sounds like the O-Ring is the Cause of your Problem. The Brass Seat is Not Replaceable and the O-Ring should be a Tight Fit. Sometimes you can Use a Light Coating of Blue Thread Locker Around the O-Ring before Installation and Clean Any Excess Thread Locker. Allow the Thread Locker to Dry for 1 Hour. Now you can Finish Assembling the Carburetor and Use the Engine. Also, You can Purchase the Carburetor Kit (or Just the Float Needle Valve Kit) that Uses the Single, Rubber Tipped Needle Valve and Not Use the O-Ring Seat. The Rubber Tipped Float Needle Valve is Longer and Uses the Brass for the Seat. This Style Float Needle Valve is the Preferred Way to Correct your Problem. You can View a Breakdown/IPL of the Engine at this Site Addy; http://www.briggsandstratton.com/maint_repair/manual_and_more/doclist.aspx?categ... and Enter the Model Numbers (190707
) and the First 4 Type Numbers (2518) in the Appropriate Boxes and Click GO. Then Select Download PDF. If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.
Good Luck
