Small Engines (Lawn Mowers, etc.): Troy-Bilt LTX-1842 Lawn Tractor w/18H B&S Engine, head valve engine, twin cylinder engines

Question
When i try to start, the motor only turns over a small amount and no futher, sounds like a dead battery. I've changed the battery and installed a new starter with the same results. Any suggestions

Answer
Hello Roger:

Usually if the Battery and Starter are Good and if this is an OHV (Over Head Valve) Engine, then Reset the Valve Clearance. Usually when the Engine Turns 3/4 of a Turn then Slows/Stops During the Cranking, the Valve Clearance is Off and the Engines Compression Release for Easy Starting can Not Operate Properly. **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. Now Loosen the Valve Adjuster Locks and Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .007in - .009in. I have had Better Performance Out of the Mowers and Less Burnt Valves Using these Settings. Be Sure the Piston is at TDC on the Compression Stroke.**  For the OEM Valve Clearances; Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. 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
