Small Engines (Lawn Mowers, etc.): B&S Hard to/wont start, twin cylinder engines, valve clearance

Question
I have a murry with a 14.5 B&S. When I try to start it, it acts like the timing is off. Very slow turn then seems to stop when hits compression. I have changed battery's(New) and starters(used) and it still does the same thing. Now it won't start at all and I am at my wits end
Please help
Thanks
Fred

Answer
Hello Fred:

Send me the Model and Type Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model and Type Numbers. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. If this is an OHV Engine, then Reset the Valves. 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 .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
