personally I would stay as far from a shop as I can, with the exception of machine shops. As I don't have the $100,000 worth of machines I would need. Even then I have had horrible experiences. Also do you know the neighbor? Just because someone rebuilt it doesn't mean it was done even remotely correct. You first need to get a manual. Was it full after you changed the oil? Did you check? What have you done already, did you check the oil and come straight to the forum? Or did you check around for where it might have went. You have a huge advantage over us, as you can actually go look at your engine, These engines have been known to leak a lot of oil. Oh did I mention you should get a manual, most especially since you have no engine experience. I would suggest you get a manual. (all the references to getting a manual wasn't a typo) Other than that What Mr. Lang has suggested is 'bout it. Now if you are emitting a huge mosqito fogger smoke screen, that would be a whole other story, but (oh I hate to do this) for now I am assuming you would have mentioned that part. (the smoke I mean)
