Craftsman Riding Lawn Mower (Hard to Start)

I have a Craftsman Lawn Tractor (Model # 917.275.400). Upon turning the key to start it up, the motor turns maybe one to one and a half revolutions and then the solenoid starts making a rapid clicking noise and the starter and motor both quit. I have replaced the battery and all terminals and wires are tightly secures and cleaned. I can jump start it with a car, but prefer to figure out the issue. I have also adjusted the valve compression to .004 on both intake and exhaust valves. I hooked up a voltage meter to the battery and the volts are at 12.7 before turning the key to start. After I turn the key to crank the engine, the volts drop substantially (to almost 3 volts at times) and that's when the starter seems under a heavy load. I have not check the solenoid by have unmounted the starter motor from the motor while still hooked up to the solenoid and the starter ran fine after turning the key to start. Is there something else I'm missing? I've seen where the valve compression specs for an 18hp briggs and stratton are .003 for intake and .005 for exhaust and others have said .004 for both. Will that make a huge difference/solve this problem?

Riding mowers are awesome to have especially in fall season. But when it starts to have issues it can be frustrating. While you are waiting on an expert to answer your question, I suggest you set service with a sears technician. I have attached the link below. Have a nice day!
