If you see drips from that black rubber boot area it is the oil pressure switch. It could have a leak and a loss of oil but would not keep it from cranking or starting. But check your oil level to be sure it is not low, now that you have seen leaking.
The throttle cable itself won't cause a no start. Just don't open the throttle while cranking, that usually works best.
If it will crank all the time, but not fire up then it is fuel or electrical related.
Only a biker knows why a dog sticks his head out of a car window.
