Small Engines (Lawn Mowers, etc.): Snapper tractor wont start, twin cylinder engines, snapper lawn tractor

Question
My Snapper lawn tractor (LT150H33IBV)with a B & S engine (281H00)
won't start. Battery is good and when I turn the key the flywheel turns slightly and then stops. There is a clicking noise. I tried to turn the flywheel slightly by hand when cranking but this didn't help. Thanks for any suggestions.

Answer
Hello Kevin:

>>Sorry for the Delay. I had to Perform Upgrades to my PC and it Took a While. The PC had Not been Upgraded in More than a Year and some of the Upgrades Took a While to Download and Install. I also had my PC in Pieces for Internal Cleaning.
>>From your Description it Sounds like the Starter May be Dragging, The Crankcase is Overfilled with Oil or the Valve Clearances May Require Setting.
>>First I Suggest you have the Starter Load Tested at your Local Auto Parts Retailer. Advance or NAPA can Usually Test them for you.
>>If the Starter is Good and the Crankcase is Not Overfilled, then Set the Valve Clearances.
>>The Following is a Basic File I made for Setting the Valve Clearances. Any Input is Appreciated.
>>**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).
>>Check the Push Tubes and make Sure they are Not Bent.
>>Set the Cylinder you are Setting the Valves on to Top Dead Center on the Compression Stroke When Setting the Valve Clearance. Now Loosen the Valve Adjuster Lock and  Using a Blade Style Feeler Gauge, Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .006in - .008in. Loosen and Tighten the Rocker Arm and the Feeler Gauge is Placed Between the Rocker Arm and the Valve Top where the Rocker Arm Pushes on the Valve.
>>***BE SURE TO TIGHTEN THE ADJUSTER LOCK AFTER YOU HAVE THE PROPER VALVE CLEARANCE***
>>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.**
>>If you Remove the Valve Cover and then Turn the Engine by Hand, you can Watch the Intake Valve Movement. When the Intake Valve Closes, the Piston will Just Starting the Compression/Power Stroke.
>>On Some Engines you can Us a Straightened Coat Hanger and Feel the Piston.
>>Be Careful and Don't Jam the Wire in the Cylinder. Usually the Piston will Push the Wire Out of the Spark Plug Hole with No Problems.
>>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. Be Safe and Happy. Thanks.

Good Luck
