I just got my new Metro 48" delivered today. Gave it a run around for about 10 minutes and when I was done I noticed some engine oil on top of the mower deck. It appears to have blown out of the engine at some point. Couldn't quite tell. The engine is a 15HP Kawi. I don't think this is normal, but is this something that happens and will stop (when gaskets seal) or is this a problem? Funny think is that I noticed a Metro 48" at the dealer sitting outside with oil in the same spot - different mower though as that has pistol grips. That is what is making me think it may be something that happens during break-in. Any thoughts?
