So I have a scag walk behind with a Kawasaki FB460V engine. So the issue is when I tilt the mower towards the controls oil leaks out of the bottom of the engine onto the pulleys. it only has a slight leak when level maybe 5 drops in three days but when tilted it pretty much pours out I cleaned it up under the mower and cant really tell where it really coming from I think it is coming from the seal where the shaft enter the engine. Any help will be appreciated. Can I pull off both pulleys with no issues (special adjustments needed when put back on) also if it the seal how hard is it to replace?
