I have a 22HP Kawasaki Scag Turf Tiger. Does anyone else have a problem with their Scags leaking oil? It leaks like a siv out of front of engine. I can't tell where it is because there's a cover there. I think it's leaking where the flywheel is. Do I have to actually pull the motor apart to repair this, or is it an easy repair like a valve cover or something? I'm putting in almost 1/2 qt a week. Thanks!
