Hello Robert:

Is the Battery Fully Charged/New? Check the Connections for Good Contact. Disconnect and Reconnect the Connections Several Times. This Tends to Clean the Mating Surfaces Enough to Make a Connection. Use a Volt Meter and Check the Voltage to the Starter when the Key is Held in the Start Position. There Should be 12.4VDC Minimum in the Battery and 11.0 - 11.4VDC Minimum When the Key is Held in the Start Position. 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 (123K05-0344). Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck,
John

Answer
There may be in interlock (safety) on the engine brake assembly.  Have you checked the wires connected to the engine, especially the wires near the engine shut-off cable?  There is a micro-switch on the engine shut-off assembly.

When you squeeze the engine shut-off lever, does the cable pull the engine shut-off fully open?  Sometimes the cable can stretch or wear where it does not fully move the engine shut-off arm.

Let me know if the engine shut-off cable and wiring are working.

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
