Gary I have a couple comments about questions 3 and 4.
The crankcase breather can be the cause of wierd drips of oil. Anouther thing to look at is the QL series uses rubber motor mounts as those mounts get old and break down it allows the engine oil pan to rub. It can wear a hole right through the pan.
On the deck belt not holding, normally those belts will hold enough to kill a 14 horse engine. either your mule drive or deck belt tighteners are weak or froze up.
