why won't my mtd b&s 14hp turn over (addendum)?

Good advise Rick but I just bought a new starter for it and all I can get is the starter engaging to the flywheel but it only bumps it and the engine does not turn over. There is plenty of juice in the battery and as I said the starter is doing its part. I noticed that there are two wires that run up into the engine case just above the starter and seem to run back to either the switch or the solenoid I can't really tell. Could these two wires have something to do with the engine turning over? Also, if a pin is sheered off of the blades that keep them secured or balanced would that keep the engine from turning over as a safety precaution? All I am getting is click like the battery is dead but you can see the starter kick in.
