Nice work! Just don't sand any holes in the block! i seen some pics of a guy who bought a 2 stroke engine kit, and the head bolts were exposed throughout the entire jug! Meaning, you can see the bolts through the fins! I can't believe the would ship something like that. It's just amazing how here we are in 2010, and all companys' can think about is " How do we save more money", instead of "How do we make the customer appreciate, respect, and hopefully continue buying,and spreading the word about our great product". In the 50's, it wasn't like that at all. Mostly everything that was made out of metal was usually forged, not cast and was more common to be made here in USA.
