Small Engines (Lawn Mowers, etc.): Setting OHV, twin cylinder engines, craftsman lawn tractor

Question
My husband has a craftsman lawn tractor 24.0, 42" electric start 6 speed transaxle. Model No. 917.28725. Brigg engine model#445677-0827-E1. He needs to set the OHV. It is to tight and he needs to reset it. The part is way to expensive and we can NOT afford it. Can you PLEASE help us. This is my husband's lively hood and we need help. Thank you for your time.

Answer
Hello Lisa:

What Part? There are No Parts Required to Reset the Valves. Here are the Valve Setting Instructions. I Do Not Use the Setting Called for by the OEMs. I have Found that the Following Works Best. Remove the Valve Cover (on the Dead Cylinder for Twin Cylinder Engines). Set the Cylinder you are Setting the Valves on to Top Dead Center (Both Rocker Arms will have Play in them when the Engine is at TDC) When Setting the Valve Clearance. On Some Engines you can Insert a Pencil Into the Spark Plug Hole and Carefully Turn the Engine Until the Pencil Stops Coming Out of the Engine. This is TDC Also. Now Loosen the Valve Adjuster Locks and Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .008in - .010in. I have had Better Performance Out of the Mowers and Less Burnt Valves Using these Settings. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
