Briggs & Stratton 14.5 hp New starter engages. Engine gets to compression & stops. Sometimes it will start. Other times it won't. Also, has new battery & cables.
Incorrect valve tappet clearances, this will stop the auto deco valve in the engine working.
Its the valve lash adjustment on these motors its very common there is a torqx screw on center of the adjutsters to lock it down undo this and adjust the valve lash on both to .004 with the engine just past tdc (cam on time) it works fine with .004 on both valves

Try a siple oil change, over time the oil can becoem like sludge. this will prevent the mootr from turning freely.

Andy, Hi, well I would start at the Starter myself, usually the thing called the "Bendix" spring jams up and stops it dead. Pull of the Starter, and power it up, off the unit. This will show you if it snaps in and out.
Sometimes a few judicious whacks with a soft hammer will sometimes free up the spring, if thats is indeed what's wrong. Anyway try that first. before any disassembly.
Make sure the Motor CAN actually be turned, by turning the flywheel, this should show you if the Motor is "Free" enough to move.
Also check ALL electrical connection to the starter. Use a meter and see if you are actually getting a voltage to the starter too. make sure your starter battery is good too.

Try spraying a little starting fluid in the intake of the carb. If the engine starts for a few seconds and then dies, it's a fuel delivery problem. Let me know the results.
