Questions & Answers for Briggs and Stratton 44N877-0007-G1

My riding mower is now surging. I've replaced spark plugs,air filter,fuel filter,oil and oil filter ???

Daniel for model number 44N877 asked on 2023-05-17

Hi Daniel, Thank you for writing. Remove all the fuel lines and blow through them looking for a blockage. Also when the engine is running spray some carburetor cleaner into it a little at a time so you do not stall the engine. Do this for a minute or 2. If the problem persists then remove and rebuild the carburetor as there is more than likely some dirt in their carburetor causing this issue. Clean everything with carburetor cleaner then reassemble. After rebuild is complete you will need to set up the carburetor. 1. Loosen the large set screw on top of the air filter with a flathead screwdriver and remove the air filter from the carburetor. 2. Locate the idle adjustment screw on the side of the carburetor. Gently turn the screw clockwise with a screwdriver until the valve touches the seat. Then, back the screw off counterclockwise one-and-a-half turns. 3. Look on the opposite side of the carburetor, for the high-speed adjustment screw -- if your carburetor has one. Gently turn the screw clockwise until the valve touches the seat, then back this screw off one-and-a-half turns as well. 4. Check to see if your engine has a large bowl on the bottom side of the carburetor that houses the float. If so, it will have a single screw on the bottom of the bowl. Turn the screw clockwise until it stops turning, then back it off for one-and-a-half turns. 5. Replace the air filter on top of the carburetor and secure it by tightening the screw in the centre of the air filter. 6. Start the engine and let it half-throttle for about five minutes to warm up. Then, slowly turn the idle adjustment screw -- which you adjusted in Step 3 -- clockwise until the engine begins to slow. Note the position of the screw and then begin turning the screw counterclockwise. The engine will normalize, then eventually will begin to slow once again. Note the position where it begins to slow a second time and rotate the screw clockwise to a point halfway between the two positions where the engine began to slow. You have now fine-tuned the idle adjustment. 7. Increase the throttle to full speed. Repeat the adjustments you made on the idle screw on the high-speed screw -- on the opposite side of the carburetor from the idle screw. 8. Test the engine under varying workloads. If the engine runs roughly under any conditions, adjust the idle or high-speed screw to fine-tune the adjustments. I hope this helps and good luck with your repair.
