Small Engines (Lawn Mowers, etc.): Lawn-Boy R8237, carburetor body, adjustment screws


Question
Lately me mower doesn't want to keep running until really warmed up and then it does not have its usual power. It starts on the second or third pull, but then start to die. I hit the primer and it will keep running. It seems to take about 5 minutes to get to the point where I don't have to  keep priming, but still have to be careful with load. If I use the power drive on the wheels, it still starts to die if long grass is encountered. Even when running fairly well after hot, it still varies in speed. Don't know if this is a fuel supply issue orsomething else

Answer
Hello Gary:

Remove the Muffler and Ensure the Exhauet Port and the Muffler are Not Clogged with Carbin. Check the Muffler for a Spark Arrestor Screen, Also. If the Exhaust Port and Muffler are Clear, then Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I Use Gunk). I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning. You Only have to Remove the Bowl, Float Pin, Float and Needle Valve and Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed. Then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts. Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidential Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. You can View a Breakdown/IPL of the Mower at this Site Addy, https://lookup3.toro.com/partdex/default.cfm?xCaller=LawnBoy and Select Start Parts Viewer. Then Enter the Model Numbers and Click Search. Then Select View Assembly Drawings. Then Select the Component you Wish to View. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
