I have a Husky with a 21 HP Kohler Courage SV-610 engine. I have changed oil, oil filter, air filters, fuel filter, and sparkplugs, replaced two carburetor gaskets and the heat deflector gasket, put in fresh fuel, and the engine was running rough. I adjusted the Low Idle screw a bit, and it made the engine run smoother at full speed, I am working alonme, and did not have enough weight to put in the seat to keep it running so I could perform the recommended procedure. I have adusted the screw several more times, and the problem is now worse instead of better. Is there a strting pint for that screw, such as 1 & 1/2 turns clockwise from the furthest position it will go counterclockwise?

Google: Kohler engine owners & service manuals, click on first site, enter SV610 in model box, scroll down page for service manual & click. Hope this helps.
